Abstract

The present invention relates to the technical field of catalyst preparation, and in particular to a preparation method and an application of a nickel phosphide-ruthenium phosphide/foamed nickel three-dimensional self-supporting electrode material. The preparation method comprises the following steps: 1) preparing a foamed nickel self-supported nickel-ruthenium layered double-metal hydroxide; and 2) preparing a nickel phosphide-ruthenium phosphide/foamed nickel three-dimensional self-supporting electrode material. An application of the nickel phosphide-ruthenium phosphide/foamed nickel three-dimensional self-supporting electrode material in electrolysis of water. The preparation process in the present invention is convenient and simple, the cost of an electrocatalyst can be greatly reduced, excellent performance is achieved in the aspect of alkaline electrocatalytic hydrogen evolution, excellent catalytic performance is also shown in alkaline electrocatalytic oxygen evolution and full hydrolysis, a three-dimensional porous foamed nickel carrier has excellent conduction performance, the loading capacity of active sites can be improved, and the transfer speed of electrons and protons can be accelerated. An in-situ growth method can effectively improve the interaction between the nickel phosphide-ruthenium phosphide and the carrier foamed nickel, thereby enhancing the electrocatalytic stability of the nickel phosphide-ruthenium phosphide and the carrier foamed nickel.
