Abstract:

Layered molybdenum disulfide(MoS2) has attracted much attention in electrochemical hydrogen generation due to its unique physicochemical properties. The hydrogen inert surface of MoS2 results in the inferior hydrogen evolution reaction(HER) activity to Pt in both acid and alkaline media. Confining single atoms(SAs) on MoS2 is a promising method to activate the basal plane, making MoS2 an advanced HER electrocatalyst. Herein, this perspective starts with the structure of SA-MoS2, and discusses the role of SAs for enhanced catalytic activity. Subsequently, synthesis methods, characterization techniques and recent progress of SA-MoS2 are summarized. It highlights the importance of surface defects induced by SAs in activated basal plane to achieve high electrocatalytic performance. Finally, based on the progress of SA-MoS2 in HER, this perspective presents general guidelines and research challenges in this promising field.
