Abstract

Tremella-like MoS₂ nano-sheets were directly synthesized on transition metal sulfides (TMS) via a solvothermal method, displaying extreme activities towards hydrogen and oxygen evolution in alkaline condition. The enhanced performance is attributed to the synergistic effect between the MoS₂ shell and TMS yolk, expanded interlayer distance and the hierarchical structure.
