Solid state pelletizing for the synthesis of new Bi-doped strontium molybdate and its development as a photocatalytic precursor for Rhodamine B degradation.

ABSTRACT

At present, climate change, urbanization and globalization are the main factors that affect water quality, the primary vehicle for the translocation and permanence of emerging pollutants, resulting in a danger to human health and the environment. The scheelite-type compounds have been investigated owing to their interesting photocatalytic properties in water purification trough the removal of different organic and inorganic pollutants. In this article a method solid state for doping of bismuth(III) in systems Sr1-3xBi2xΦxMoO4 with (0 ≤ x ≤ 0.225) were obtained and, likewise its pelletizing process. Subsequently, these new materials were spectroscopically characterized with photocatalytic properties and finally is describe its development as oxidant against Rhodamine B. This work can be used for the synthesis of new Bi-doped strontium molybdates, which the best photochemical properties are chosen and, in turn, it is experimentally shown how can favor its absorption in the visible region. These electronic properties can be used in near studies, for to compressive the role of bismuth(III) in sheelite as photocatalyst and, to implement its use in the degradation of persistent pollutants that affect the world's water resources.•The doping of bismuth(III) for systems Sr1-3xBi2xΦxMoO4 modified the GAP absorption and this catalytic properties using this new solid state method.•The degradation of Rhodamine B for systems Sr1-3xBi2xΦxMoO4 as case study using of this methodology allows multiple applications associated with climate change such as the degradation of emerging pollutants and the sensitization of semiconductors with solar claims.•The role of bismuth(III) in these systems can be harnessed to design similar materials with photocatalytic properties.
