Recent advances in layered transition metal dichalcogenides for hydrogen evolution reaction

Hydrogen is considered to be a crucial clean energy for the future. As alternatives to Pt for the catalysis of the H-2 evolution reaction (HER), transition metal dichalcogenides (TMDs) have shown great promise. In particular, significant new developments involving 2D layered TMDs have been recently reported. This highlight focuses on recent advances in the synthesis of 2D MoS2 and WS2 sheets, and their performance in the catalysis of the HER.
