MXene-supported Co3O4 quantum dots for superior lithium storage and oxygen evolution activities.

A novel hybrid, composed of Co3O4 quantum dots supported on Ti3C2Tx (MXene) nanosheets, exhibits a strong synergetic effect, and shows superior lithium storage (capacity = 766.5 mA h g-1 at 2 A g-1 after 400 cycles) and oxygen evolution (overpotential = 340 mV at 10 mA cm-2) activities.

Creating a synergistic interplay between tubular MoS2 and particulate Fe3O4 for improved lithium storage.

A novel three-dimensional MoS2@Fe3O4 nanohybrid, composed of tubular MoS2 uniformly and densely decorated with particulate Fe3O4, is constructed, which exhibits significantly improved lithium storage performances through an impressive synergistic interplay between the two active materials.
