Abstract:

As a green hydrogen production technology, electrolyzed water splitting has received lots of attention.Design and development of high-efficient and low-cost electrocatalysts,which are suitable for full pH(pH=0-14) media,can reduce ener-gy consumption,simplify device construction and optimize production process.MoS2 has been considered as one of the pro-mising materials for electrochemical hydrogen evolution,due to its tunable electronic structure and the most suitable thermo-dynamic activity except for precious metals.The current research progress of MoS2-based pH-universal catalysts for electro-chemical hydrogen evolution reaction was reviewed,such as modulating physical property of intrinsic MoS2,surface engineer-ing with atom doping,and interface engineering.The corresponding catalytic mechanism was clarified.It was revealed that preparation of catalysts with both hydrogen evolution activity and stability at high current density in all-pH range would be the tendency of electrocatalytic materials.It was also proposed that activation of inert basal plane for multi-level structural MoS2 materials,enhancement of the whole electroconductivity,anchor of single atoms precisely,and encapsulation of active materials with porous carbon would be the fundamental strategies for designing efficient pH-universal catalysts.

Key words: MoS2, pH-universal, electrocatalytic hydrogen evolution, electrolysis of water
