Abstract

The invention provides a cerium-doped tungsten phosphide submicron sphere composite material, a preparation method and application thereof. Cerium in the cerium-doped tungsten phosphide submicron sphere composite material is uniformly doped in tungsten phosphide submicron spheres, and the cerium-doped tungsten phosphide submicron sphere composite material is prepared by loading cerium-doped tungsten oxide submicron spheres on a substrate through a solvothermal synthesis method and then phosphating the cerium-doped tungsten oxide submicron spheres. The preparation process adopted by the invention is simple, the obtained composite material has uniform particles, and when used as an industrial water electrolysis catalyst, the composite material has high charge transmission speed, enhanced hydrogen adsorption capacity and desorption capacity, improved electro-catalytic hydrogen evolution activity, excellent catalytic performance, and strong stability.

Description

technical field

[0001] The invention relates to a composite material, in particular to a cerium-doped tungsten phosphide submicron sphere composite material and its preparation method and application. Background technique

[0002] Energy crisis and environmental pollution are the urgent problems facing the current society. The production of hydrogen by electrocatalytic water splitting is an effective way to solve the above crises. However, in the actual process of electrocatalytic water splitting to produce hydrogen Therefore, obtaining high-efficiency hydrogen evolution electrocatalysts to improve the efficiency of electrocatalytic hydrogen evolution reactions has become the key to the development of hydrogen production by electrolysis of water. The currently recognized high-efficiency hydrogen evolution electrocatalysts are platinum-group noble metals, but precious metal reserves are scarce and expensive, which greatly limits their wide application. Therefore, it is urgent...
