ABSTRACT
The key to electrocatalytic hydrogen evolution technology is the preparation of catalyst with excellent performance and low cost. MoSe2 and MXene possess the 2D layer structures similar to graphene, thus existing much excellent and special performance. Herein, the preparation methods of MoSe2 and its application of electronic hydrogen evolution reaction are introduced. The ways and theories to enhance its catalytic activity via importing defects, phase-change regulation and compositing conductive base are discussed in detail. Additionally, MXene, the emerging 2D materials, is presented about its structure, performance and preparation methods and different types of MXenes are exemplified about their various performances and applications. Finally, the composite methods of 2D materials are introduced while its huge contributions for improving electrochemical catalytic property and principles are discussed.
