Recent Progress in Metal Phosphorous Chalcogenides: Potential High-Performance Electrocatalysts.

Since the discovery of graphene, research on the family of 2D materials has been a thriving field. Metal phosphorous chalcogenides (MPX 3 ) have attracted renewed attention due to their distinctive physical and chemical properties. The advantages of MPX 3 , such as tunable layered structures, unique electronic properties, thermodynamically appropriate band alignments and abundant catalytic active sites on the surface, make MPX 3 material great potential in electrocatalysis. In this review, the applications of MPX 3 electrocatalysts in recent years, including hydrogen evolution reaction, oxygen evolution reaction, and oxygen reduction reaction, are summarized. Structural regulation, chemical doping and multi-material composite that are often effective and practical research methods to further optimize the catalytic properties of these materials, are introduced. Finally, the challenges and opportunities for electrocatalytic applications of MPX 3 materials are discussed. This report aims to advance future efforts to develop MPX 3 and related materials for electrocatalysis.
