"It's just the joy of existing": A Photo Elicitation of LGBTQ+ Students' Healthy Intimate Relationships.

This study of LGBTQ+ college students highlights and amplifies the experiences of their healthy intimate relationships. College represents a pivotal time for personal and relationship development for many students, and seeing the positive ways students with historically minoritized gender and sexual identities navigate relationships has value for understanding how sexuality manifests within the current culture. Using a critical constructivist perspective and photo elicitation methods, the study includes students' narratives and visual presentations of their lived experiences thriving in healthy intimate relationships. The findings included three specific areas that supported students' thriving: self-work and self-awareness, fluidity and flexibility, and communication. These findings, and students' relationship images highlight the ways that they thrive through continual affirmative consent and responsibility to themselves and their relationships. Together, these findings provide possibility models to support imagining and educating about LGBTQ+ students' healthy intimate relationships. Findings have potential for informing trainings and resources for LGBTQ+ students, enhancing relationship education by challenging oppressive norms that influence all students, and for questioning the ways university regulations inhibit participants' agency for celebrating their intimacy.

Exploring the gender-sensitive feelings of nurses towards residents with intimate and sexual needs in dementia nursing care.

INTRODUCTION: Person-centered care emphasizes close care relations regardless of gender. However, when residents with dementia express intimate or sexual needs, nurses may struggle with their own emotions and need to include personal boundaries. METHODS: 277 (vocational) nurses from 25 Dutch nursing homes completed a survey, including the Feeling Word Checklist for a resident with perceived sexual needs and another for a resident with perceived intimate needs. RESULTS: Positive-nurturing sentiments towards residents prevail, yet residents expressing intimate needs elicit higher levels of positive-nurturing and lower levels of negative emotions than those with sexual needs. Male residents, who expressed more pronounced sexual needs, received less affection and interest from female nurses who felt especially close to female residents with intimate needs. CONCLUSION: Close care relations established through nurses' personal emotions inadvertently introduce gender-sensitive and differing emotions towards residents. Nurses' capability to include personal boundaries benefits the relationship and well-being of both parties.

Grief and Sexual Intimacy: Exploring Therapists' Views of Bereaved Clients.

The interaction between sexual intimacy and grief remains unexplored despite its potential to offer valuable insights into how individuals, couples, and society perspectives shape bereaved individuals' sexual intimacy. Through semi-structured interviews with ten clinical psychologists and psychotherapists specialized in grief therapy, this study explores the impact of grief on sexual intimacy, the challenges faced by bereaved individuals, and the role of sexual intimacy in the grieving process. The study also investigates therapists' approaches to addressing sexual intimacy within grief therapy sessions. Findings reveal that grief often disrupts sexual intimacy, affecting individuals' ability to engage emotionally and physically with their partners. Factors such as secondary loss, emotional availability, traumatic experiences, and the nature of the loss contribute to difficulties in resuming sexual intimacy. Nevertheless, the helpful role of sexual intimacy in grief was also highlighted. Therapists note the significance of communication, mutual empathy, and understanding in overcoming these challenges, advocating for therapy to address these issues comprehensively. Moreover, therapist-related, client-related, and shared factors hindering the exploration of sexual intimacy in grief therapy were identified. Strategies for managing these challenges include normalizing discussions around sexual intimacy and death, integrating systemic approaches into therapy, and providing training in sexuality or sexual therapy for grief therapists. Overall, this study underscores the importance of recognizing and addressing the interplay between sexual intimacy and grief to support bereaved individuals effectively. Insights from therapists shed light on potential avenues for enhancing clinical interventions and fostering awareness of the complex dynamics surrounding bereavement and sexuality.

Changes in Spousal Intimacy in Women Suffering Trauma Symptoms from Domestic Abuse: A Culturally Embedded Intervention Study in Pakistan.

While emerging research is highlighting the significant effects of culture on marital and family relationships, studies investigating relationship intimacy and abuse in non-Western cultures are non-existent. This investigation assessed relationship intimacy in Pakistani women experiencing trauma symptoms (PTSD) from domestic abuse (DA) who received a culturally informed trauma intervention in a context that differs greatly in values and assumptions about marital relationships relative to Western traditions. Forty women meeting inclusion criteria were assessed on domestic violence type and characteristics (both victim and perpetrator characteristics), PTSD symptomology, and three aspects of relationship intimacy: engagement, communication, and shared friendships. PTSD symptomology and relationship intimacy were reassessed post-intervention. Results indicated significant changes in engagement and communication intimacy following the intervention, with engagement decreasing and communication increasing. The third aspect of intimacy, namely, shared friendships, showed no change. Engagement and overall intimacy showed significant negative correlations with physical abuse, though not with sexual or psychological/emotional abuse. These findings are interpreted within a cultural context where women have few options for leaving an abusive relationship. As such, the results highlight the importance of culture when studying facets of intimate relationships and the need to use culturally informed assessments to better understand the experience of intimacy within abusive relationships.

Factorial Trial to Optimize an Internet-Delivered Intervention for Sexual Health After Breast Cancer: Protocol for the WF-2202 Sexual Health and Intimacy Enhancement (SHINE) Trial.

BACKGROUND: Although most survivors of breast cancer report substantial sexual concerns following treatment, few receive support for these concerns. Delivering sexual health care to survivors of breast cancer via the internet could overcome many of the barriers to in-person treatment. Even when delivered remotely, survivor time constraints remain a leading barrier to sexual health intervention uptake. OBJECTIVE: Guided by the multiphase optimization strategy methodological framework, the primary objective of this study is to identify the most efficient internet-delivered sexual health intervention package that is expected to provide survivors of breast cancer the greatest benefit with the fewest (and least-intensive) intervention components. This study aims to determine how intervention components work (mediators) and for whom they work best (moderators). METHODS: Partnered, posttreatment adult female survivors of breast cancer (N=320) experiencing at least 1 bothersome sexual symptom (ie, pain with sex, vaginal dryness, low sexual desire, and difficulty with orgasm) related to their breast cancer treatment will be enrolled. Clinic-based recruitment will be conducted via the Wake Forest National Cancer Institute Community Oncology Research Program (NCORP) Research Base. Participants will be randomly assigned to 1 of 16 combinations of four intervention components with two levels each in this factorial trial: (1) psychoeducation about cancer-related sexual morbidity (receive either enhanced vs standard versions); (2) communication skills training for discussing concerns with health care providers (received vs not received); (3) communication skills training for discussing concerns with a partner (received vs not received); and (4) intimacy promotion skills training (received vs not received). Cores will be fully automated and implemented using a robust internet intervention platform with highly engaging elements such as animation, video, and automated email prompts. Survivors will complete web-based assessments at baseline (prerandomization time point) and again at 12 and 24 weeks later. The primary study aim will be achieved through a decision-making process based on systematically evaluating the main and interaction effects of components on sexual distress (Female Sexual Distress Scale-Desire, Arousal, Orgasm) and sexual functioning (Female Sexual Function Index) using a generalized linear model approach to ANOVA with effect coding. Mediation analyses will be conducted through a structural equation modeling approach, and moderation analyses will be conducted by extending the generalized linear model to include interaction effects. RESULTS: This protocol has been reviewed and approved by the National Cancer Institute Central Institutional Review Board. Data collection is planned to begin in March 2024 and conclude in 2027. CONCLUSIONS: By identifying the combination of the fewest and least-intensive intervention components likely to provide survivors of breast cancer the greatest sexual health benefit, this study will result in the first internet intervention that is optimized for maximum impact on the undertreated, prevalent, and distressing problem of breast cancer-related sexual morbidity.

The mediating role of mentalization and integrative self-knowledge in the relationship between childhood trauma and fear of intimacy.

Introduction: Since intimacy is a fundamental human need within social relationships, and recognizing that a fear of intimacy correlates with various negative consequences, it becomes crucial to examine the origins and factors that contribute to addressing this issue. This research aimed to investigate the mediating roles of mentalization and integrative self-knowledge in the link between childhood trauma and the fear of intimacy. Methods: Conducted as correlational descriptive research, our study incorporates a total sample of 303 adult women and men participants aged 20 to 50 in Tehran using the convenience sampling method. They completed the Fear of Intimacy Scale (FIS), the Childhood Trauma Questionnaire (CTQ), the Mentalization Scale (MentS), and the Integrative Self-Knowledge Scale (ISK). To analyze the research data at the descriptive level, frequency, percentage, standard deviation, and Pearson's correlation coefficient were used, while path analysis tested our hypotheses in SPSS version 26 and AMOS version 24. Fit indices were used to check the model's fit, and the mediation test was performed using the bootstrapping method. The fit indices revealed an excellent fit of the model with the data (χ2 = 1.51, χ2/df = 1.51, p = 0.219; RMSEA = 0.05; SRMR = 0.02; CFI = 0.99; NFI = 0.99; TLI = 0.99). Results: Results indicate mentalization fully mediates the childhood trauma-fear of intimacy relationship (ß = 0.14, p < 0.01). However, the indirect relationship between childhood trauma and fear of intimacy through integrative self-knowledge was insignificant. The results also showed that the path coefficient from mentalization to fear of intimacy was negative and significant (ß = -0.41, p < 0.001), while the path coefficient from integrative self-knowledge to fear of intimacy was not significant (ß = -0.02, p > 0.05). Discussion: Based on the current findings indicating the complete mediation of mentalization and the insignificance of the mediation of integrative self-knowledge, we can deduce that enhancing the capacity for mentalization holds promise in effectively addressing intimacy-related issues. Overall, the study suggests mentalization effectively predicts the relationship between childhood trauma and fear of intimacy. This, in turn, may mitigate the detrimental effects of challenging childhood experiences on an individual's ability to engage in intimacy and cultivate emotional closeness.

A Meta-Synthesis on Sexuality in Persons with Dementia Mapped Using the Model of Human Occupation.

Dementia affects the individual's functional ability including sexual activity. Limited understanding is available to support sexual health practices. This meta-synthesis review aimed to identify the gaps in the study of sexuality in dementia using the Model of Human Occupation (MOHO). Electronic searches utilizing six databases for existing articles involving persons living with dementia, care partners, and healthcare workers. The result showed that available studies primarily explored sexuality from the viewpoint of spouses of persons living with dementia. The volition domain of MOHO was the most explored provides a deeper understanding of volition on intrinsic perspective on sexuality in people with dementia. The environment domain was the least explored, highlighting healthcare professionals' need for social support and training. The topic of sexuality remains sensitive, limiting the availability of evidence-based interventions in this area.

Development of an Instrument to Assess Health and Social Care Professionals' Knowledge and Attitudes Towards Later-Life Intimacy and Sexuality (HSCP-KALLIS): A Delphi Study.

AIMS: We aimed to ascertain the content validity of an instrument to assess health and social care professionals' knowledge and attitudes towards later-life intimacy and sexuality (HSCP-KALLIS). BACKGROUND: For older adults, intimacy and sexuality are important in maintaining their quality of life and well-being. However, addressing these needs remains challenging for health and social care professionals, particularly for nursing staff providing 24-h direct care to older people with dementia or those identified as lesbian, gay, bisexual, transgender, intersex or queer/questioning individuals. Existing instruments assessing knowledge and attitudes towards later-life intimacy and sexuality are dated and fail to adequately address dementia and sexual diversity. DESIGN: A two-round modified Delphi study was conducted. METHODS: Initially, 79 knowledge and attitude items were generated through an integrative review. Panellists rated each item's clarity and importance using online questionnaires. The content validity index for the individual and overall items was calculated. The panellists' written feedback-along with their knowledge level of later-life intimacy and sexuality-was obtained. RESULTS: Panellists included health and social care professionals (n = 9); healthcare-related educators (n = 2); researchers specialising in later-life intimacy, sexuality, dementia care and sexual diversity support (n = 7); and family carers of older people with dementia (n = 2). The instrument was revised based on the feedback received. The components of dementia, LGBTIQ+ and the provision of sex worker services in healthcare settings were highlighted by the panellists. Notably, 46 knowledge and 40 attitude items fulfilled the consensus criteria for clarity and importance. CONCLUSIONS: Acceptable content validity was established for the knowledge and attitude items. Further research is required to establish the psychometric properties of the HSCP-KALLIS. This instrument has implications for clinical practice-specifically, in nursing care-by addressing issues to improve awareness regarding later-life intimacy and sexuality in healthcare settings. IMPLICATIONS FOR PRACTICE: The HSCP-KALLIS has the potential to inform the educational needs regarding knowledge and attitudes towards later-life intimacy and sexuality for health and social care professionals, specifically nursing staff. The findings of the HSCP-KALLIS can be used for the development of competencies for later-life intimacy and sexuality, establishing policies and guidelines to support older adults' intimacy and sexuality needs in health care settings.

Intersecting sex and gender diversity with sexual rights for people living with dementia in later life: an example of developing a learning framework for policy and practice.

The proliferation of literature on dementia over the last decade has begun to address the experience of LGBTQ+ people's experiences in later life. Changes in cognitive function can jeopardize the safety, wellbeing, and human rights of LGBTQ+ people if the social care workforce are not prepared or versed in responding to their unique needs. The intersection of age, cognitive function, sexual and gender diversity with the expression of intimacy and sexuality requires sensitive and respectful consideration. Yet, this is currently an under-researched and less understood area in social care practice. This paper highlights the main messages from the different bodies of contributory literature and introduces the national framework in England UK on LGBTQ+ aging and its potential for supporting workforce development to consider its flexibility in supporting services to becoming more nuanced and affirmative in these areas of practice.

Utilization of the Intimacy and Sexuality Expression Preference tool in long-term care: a case study.

Introduction: Sexual wellness plays a crucial role in an individual's quality of life, interpersonal relationships, and self-concept, particularly among older adults residing in residential aged care facilities, including those with dementia. However, there is currently a limited person-centered approach to understanding the unique preferences of each older person regarding their intimate and sexual behaviors. To address this gap, the Intimacy and Sexuality Expression Preference (ISEP) tool was developed to facilitate meaningful discussions between healthcare professionals or workers and older individuals about their intimacy and sexuality needs and preferences. This paper explores the use of the ISEP tool with residents in long-term aged care, including those with dementia via a user-centric case study. Methods: ISEP tool interviews were conducted with 14 residents in a single residential aged care facility in Queensland, Australia. Results: The study presented valuable insights and contextual information from using the ISEP tool, including an example of a resident's response, which provided recommendations for better supporting the resident. This involves engaging in supportive conversations to facilitate the exploration, implementation, and assessment of practical and actionable strategies to meet intimacy and sexuality needs and preferences. Discussion: The ISEP tool shows promise in improving care practices and addressing the intimacy and sexuality needs of older individuals in aged care facilities. However, it is important to acknowledge that the study was conducted in a single aged care facility with a small group of residents, potentially limiting the generalisability of the findings. Further large-scale studies are necessary to establish the tool's broader applicability across different care settings.

Including personal boundaries scale: development and psychometric properties of a measurement for nurses' self-efficacy toward intimate and sexual behavior in dementia care.

Background: Person-centered nursing home care recognizes the intimate and sexual needs of residents with dementia but lacks guidance for nurses to address them while effectively respecting their personal boundaries. The Including Personal Boundaries (IPB) scale was developed to complement clinical and scientific efforts to support both nurse and resident wellbeing. Methods: Through a co-creative process, theoretical principles, day-to-day experiences, and expert knowledge were integrated into an initial nineteen-item version of the IPB scale. The pilot sample comprised 297 Dutch (vocational) nurses in dementia nursing care. Results: After Principal Component Analysis, nine items with strong factor loadings (>0.6) were retained. Internal reliability measures supported the item selection, such as high internal consistency (α = 0.866) and adequate corrected item-total correlations (0.532-0.781). Conclusion: The presented IPB scale, a nine-item scale, is a short, robust measure to assess nurses' self-efficacy in their capabilities to include personal boundaries (physical and emotional) when confronted with the intimate and sexual behaviors of residents with dementia. Further validation is recommended. The IPB scale could provide valuable insights for research, clinical practice, and education.

The Negative Effect of Siblings on Perspective-Taking in Adulthood under Chinese Culture.

Evidence from Western developed countries has consistently found that children with sibling(s) showed better perspective-taking (PT) than only children. However, this was not the case in developing countries like China. Our study investigates whether the potentially hindering effect of having sibling(s) on PT persists into adulthood within the context of contemporary Chinese culture. We employed self-report questionnaires to measure PT, perceived parental care, and sibling relationships among Chinese young adults (21.93 ± 2.35 years old). Our findings indicate that in China, (1) having sibling(s) hinders individuals' PT in adulthood, (2) a potential mechanism for this effect is that having sibling(s) leads individuals to perceive less parental care during early life, and (3) for those with sibling(s), higher sibling intimacy can enhance PT, particularly among older sister-younger brother pairs. These results suggest that in developing countries such as China, while sibling(s) may diminish PT to some extent, factors like parental care and sibling intimacy can serve as protective factors that mitigate the negative impacts of sibling(s) on PT.

The Effects of Head and Neck Cancer on Relationship Intimacy in Adults: A Systematic Review of the Literature.

OBJECTIVES: This systematic literature review aimed to explore the effects of head and neck cancer (HNC) on relationship intimacy in adults and identify the current support available to patients with HNC and their partners in relation to relationship intimacy. METHODS: Seven databases (CINAHL, Pubmed, Scopus, Web of Science, SocINDEX, PsycARTICLES, Psychology, and Behavioural Science Collection) were searched using grouped terms "head and neck cancer and intimacy" and "head and neck cancer and support." Studies written in English to assess adult patients with HNC and its effects on relationship intimacy and studies assessing the use of intimacy-specific support tools/methods were included. The review protocol was registered in June 2022 with PROSPERO ID: CRD42022329614. RESULTS: Thirty publications were included within the review. Six topics emerged: relationships, communication, sexual interest, barriers, couples-based communication intervention strategies, and assessment tools. While there were positive dyadic changes observed, many patients reported negative experiences relating to changes in relationship roles, sexual issues, and poor communication with partners and health care professionals that affected intimacy. There were 5 interventions identified; of those, the results varied, with some improvements noted in psychological well-being but not necessarily sexual interest and enjoyment. CONCLUSIONS: HNC profoundly affects relationship intimacy. However, both patients and health care professionals find it challenging to discuss these issues, often leaving it an unmet need. Appropriate training and development for health care professionals that facilitate communication between clinician and patient are necessary to support conversations on intimacy needs. IMPLICATIONS FOR NURSING PRACTICE: There exists a need for patients to receive support in relation to intimacy following diagnosis and treatment, and the evidence suggests that this may be more effective post-treatment and from health care professionals who are appropriately trained. Couples' communication interventions may prove useful, but further research is required on the efficacy of combining both psychological and sexual support together.

Love Lost in Translation: Avoidant Individuals Inaccurately Perceive Their Partners' Positive Emotions During Love Conversations.

Empathic accuracy-the ability to decipher others' thoughts and feelings-promotes relationship satisfaction. Those high in attachment avoidance tend to be less empathically accurate; however, past research has been limited to relatively negative or neutral contexts. We extend work on attachment and empathic accuracy to the positive context of love. To do so, we combined data from three dyadic studies (N = 303 dyads) in which couple members shared a time of love and rated each other's positive emotions. Using the Truth and Bias Model of Judgment, we found that individuals higher (vs. lower) in attachment avoidance were less accurate in inferring their partners' positive emotions during the conversation, but did not systematically over- or under-perceive their partners' positive emotions. Our results suggest that avoidant individuals may be less sensitive to positive cues in their relationships, potentially reducing relational intimacy.

Does Web-Based Relationship Education Improve Sexual Intimacy? Initial Examination, Replication, and Exploration of Moderation in a Low-Income Sample.

Sexual intimacy, characterized as the experience between individuals of sharing general affection and sexual activity with one another within the Personal Assessment of Intimacy in Relationships inventory, is positively related to relationship satisfaction and stability. However, many studies of couple therapy have shown that it only results in small-sized (and often non-significant) improvements in sexual intimacy. Furthermore, there are numerous financial, logistical, and psychological barriers to couple therapy. Thus, the current study sought to examine whether two brief online relationship education programs (OurRelationship and ePREP) could overcome these barriers and yield similar-sized effects to more intensive couple therapy. In two independently collected samples of low-income couples (NSample 1 = 742 Couples; M AgeSample 1 = 33.19; NSample 2 = 671 Couples; M AgeSample 2 = 33.48), the current study found that: OurRelationship (d = 0.24-0.28) and ePREP (d = 0.26-0.34) produced small-sized changes in sexual intimacy relative to a waitlist control condition in both samples, the magnitude of the effect size replicated in a second sample and, with rare exception, these changes were generally not moderated by key variables of interest. Given that web-based relationship education is significantly shorter, less expensive, and more accessible than in-person couple interventions, web-based relationship education could be considered a viable candidate for couples experiencing concerns with sexual intimacy.

Intimacy Promotes Couples' Sexual Well-Being on a Daily Basis and Over One Year: The Role of Positive Sexual Cues.

There is growing interest in identifying factors that promote sexual well-being in romantic relationships. One such factor is intimacy-a process involving self-disclosure and empathic response that is positively associated with sexuality outcomes. However, most work among community couples examined cross-sectional associations in mixed-sex/gender couples using a single sexual outcome, which may not capture daily variations in intimacy and different dimensions of sexual well-being among a diversity of unions over time. Additionally, potential mediating mechanisms of the intimacy-sexual well-being association, such as attention to positive sexual cues (i.e., sexual thoughts and feelings), have been neglected. Adopting daily diary and longitudinal designs, the present study examined whether greater intimacy was associated with higher levels of positive sexual cues and, in turn, higher sexual well-being (sexual desire, satisfaction and distress). A convenience sample of 211 couples (Mage = 30.2 years; SD = 8.3; 75 sexually diverse couples) completed a survey on days of sexual activity with their partner, over a 35-day period and 12 months later. Daily results showed that intimacy was related to greater attention to positive sexual cues for both partners, which in turn was associated with their greater sexual desire and satisfaction and lower sexual distress. Longitudinal results showed that a person's greater daily intimacy was linked to their own greater sexual desire and satisfaction 12 months later via their own higher positive sexual cues, but not to their partner's cues or well-being. Findings extend interpersonal models of sexual well-being and support the role of intimacy and positive sexual cues therein.

The Machine Speaks: Conversational AI and the Importance of Effort to Relationships of Meaning.

The focus of debates about conversational artificial intelligence (CAI) has largely been on social and ethical concerns that arise when we speak to machines-what is gained and what is lost when we replace our human interlocutors, including our human therapists, with AI. In this viewpoint, we focus instead on a distinct and growing phenomenon: letting machines speak for us. What is at stake when we replace our own efforts at interpersonal engagement with CAI? The purpose of these technologies is, in part, to remove effort, but effort has enormous value, and in some cases, even intrinsic value. This is true in many realms, but especially in interpersonal relationships. To make an effort for someone, irrespective of what that effort amounts to, often conveys value and meaning in itself. We elaborate on the meaning, worth, and significance that may be lost when we relinquish effort in our interpersonal engagements as well as on the opportunities for self-understanding and growth that we may forsake.

Effect of family intervention on relapse rate of Chinese patients with alcohol-dependent.

Objective: This study explored the impact of a family intervention on the relapse rate of Chinese patients with alcohol dependence. Methods: A total of 151 male patients with alcohol dependence who were discharged from the Substance Dependence Department of the Wenzhou Seventh People's Hospital from January to December 2020 were selected. They were divided into the control (n = 73) and experimental (n = 78) groups. Patients in both groups received routine alcohol cessation treatment. Moreover, patients in the experimental group were followed up by a professional psychiatrist to carry out individual family intervention. The Family Function Rating Scale (FAD), a Self-made general information questionnaire, and the Chinese version of the Family Intimacy and Adaptability Scale (FACESI-CV) were performed. Re-drinking rate and readmission rate were assessed. Results: Family intervention could reduce relapse rate (31, 39.74%) and rehospitalization (27, 34.62%) compared with the control group. After family training, FAD factor scores were improved in the experiment group in comparison with the control group. Family training improved communication (18.2 ± 3.7), role (20.8 ± 2.5), emotional response (10.8 ± 1.8), emotional involvement (13.7 ± 1.2), behavioral control (19.8 ± 1.2), and overall functionality (23.5 ± 2.1) in the experiment group in comparison with the control group. After family training, intimacy (70.5 ± 8.7) and adaptability (64.1 ± 6.9) in the experiment group was higher than in the control group. After family intervention, Michigan Alcohol Dependence Scale (MAST) (9.21 ± 0.68) and Short-Form 36 (SF-36) (80.32 ± 4.47) in the experiment group were higher than the control group. Conclusion: Family intervention for families of patients with alcohol dependence can improve their family function, increase their family intimacy and adaptability, and reduce the rate of relapse.

Close Intimacy between PtIn Clusters and Zeolite Channels for Ultrastability toward Propane Dehydrogenation.

Propane dehydrogenation (PDH) serves as a pivotal intentional technique to produce propylene. The stability of PDH catalysts is generally restricted by the readsorption of propylene which can subsequently undergo side reactions for coke formation. Herein, we demonstrate an ultrastable PDH catalyst by encapsulating PtIn clusters within silicalite-1 which serves as an efficient promoter for olefin desorption. The mean lifetime of PtIn@S-1 (S-1, silicalite-1) was calculated as 37317 h with high propylene selectivity of >97% at 580 °C with a weight hourly space velocity (WHSV) of 4.7 h-1. With an ultrahigh WHSV of 1128 h-1, which pushed the catalyst away from the equilibrium conversion to 13.3%, PtIn@S-1 substantially outperformed other reported PDH catalysts in terms of mean lifetime (32058 h), reaction rates (3.42 molpropylene gcat-1 h-1 and 341.90 molpropylene gPt-1 h-1), and total turnover number (14387.30 kgpropylene gcat-1). The developed catalyst is likely to lead the way to scalable PDH applications.
