The invention provides a preparation method of a foamed
nickel-loaded amorphous
phosphorus doped
nickel molybdate bifunctional electrocatalytic
electrode and an application thereof, and belongs to thetechnical field of
hydrogen energy and
fuel cells. The preparation method comprises the following steps: soaking foamed
nickel into an HCl solution, removing
metal oxide on the surface, soaking the pickled foamed nickel into a
phosphomolybdic acid aqueous solution, carrying out a spontaneous oxidation-reduction reaction, taking out, washing with deionized water, and
drying for later use, therebyobtaining the foamed nickel-loaded amorphous
phosphorus-doped nickel
molybdate nanostructure. The foamed nickel is etched by using the
phosphomolybdic acid aqueous solution, and can be directly used after
drying, the material can be used as a
bifunctional electrode material for
urea electrooxidation and water and
electricity reduction; a
urea electrooxidation reaction with low oxidation potentialis used for replacing an electrocatalytic
oxygen evolution reaction, a two-
electrode urea auxiliary
electrolysis hydrogen production
system based on a
bifunctional electrocatalyst is constructed in analkaline solution, low-cost, low-energy-consumption and stable electrochemical
hydrogen production is achieved, and the method is suitable for large-scale industrial electrochemical
hydrogen production application.
