用于电解水析氢的CoP催化剂的研究进展

ompared with traditional fossil energy, hydrogen energy has the advantages of high calorific value and no pollution from combustion. Electrolytic water method can make use of solar energy and wind energy to prepare high-purity hydrogen and realize efficient utilization of resources.Transition metal phosphides (TMPs) are one of the most promising non-noble metal catalytic materials to replace electrocatalyst platinum (Pt). Among them, cobalt phosphide (CoP) has been widely studied due to its unique physicochemical properties, such as phosphorus rich and excellent electrical conductivity..At present, there are various studies focusing on improving the electrocatalytic performance of TMPs, but there are few systematic studies on improving the catalytic performance of CoP.Therefore, this paper summarizes the current research progress of cop-based electrolytic water hydrogen evolution catalysts from two aspects of preparation methods of cobalt phosphide and advanced strategies for improving electrocatalytic performance.
