2D Metallic Transitional Metal Dichalcogenides for Electrochemical Hydrogen Evolution

The preparation methods of 2D metallic transition metal dichalcogenides (MTMDCs), such as chemical exfoliation, colloidal synthesis and chemical vapor deposition, as well as their applications in electrocatalytic hydrogen evolution reactions (HER), are comprehensively discussed. In addition, challenges regarding the preparation of MTMDC nanosheets, probable routes for further improving HER performance, and future research directions are proposed.
