Roadmap and direction towards high performance MoS2 hydrogen evolution catalysts

Abstract

MoS2 are facile, stable, non-toxic, affordable materials with reasonable price, and have exhibit its superior potential in catalysis, sensing, opt electrochemical, environmental relate application1, etc. Modification of MoS2 materials has been widely applied for adjusting and formulate the relative performance in certain application field. Making vacancy, doping with other atoms, expending of the layer space, heterojunction engineering, phase engineering etc. have been applied to facilitate the catalytic hydrogen evolution performance. We make a detailed summary on MoS2 characterization methods, synthesis, HER performance, mechanisms, to make a holistic understanding on the interplay between the structure, chemistry, and HER performance, which will give directions to elevate other electrochemical reaction by MoS2.
