This review introduces typical synthetic strategies for self-supporting TMCs on metal substrates and comprehensively summarizes various metallic matrices for supporting TMC catalysts.
Transition metal chalcogenides (TMCs) are the fascinating replacement of noble catalysts in catalytic water splitting due to their unique physical and chemical properties and low cost. However, their industrial application is substantially restricted by their poor conductivity. Decorating TMCs on metal substrates to fabricate selfsupporting electrodes could be an efficient strategy for solving this problem. In this review, typical synthetic strategies for self-supporting TMCs on metal substrates are introduced in detail, while all types of metallic matrices, such as Au, Mo, Ni, Ti, Cu, etc., for supporting TMC catalysts are comprehensively summarized. By comparing the matrix types, types of loaded TMC materials, preparation strategies, application conditions, and scope, we attempt to establish rules of various metals as substrates, which may provide suggestions for material design. Finally, we briefly discuss the development directions of self-supporting TMCs@Metal electrodes for large-scale preparation and catalytic water splitting in industrial applications.
