Abstract
Disclosed are a nickel/nickel hydroxide electrode catalyst, a preparation method thereof and an application thereof, the catalyst includes a porous matrix structure and a nanosheet, where the nanosheet is doped in the porous matrix structure, a mass percentage of the porous matrix structure is 95%-99%, a mass percentage of the nanosheet is 1%-5%, and a mass density of the nanosheet is 12-15 mg/cm2; and the porous matrix structure is nickel, and the nanosheet is nickel hydroxide in β configuration. The present disclosure develops an electrode catalyst with higher catalytic efficiency and a simpler preparation method based on the Ni-based catalysts to achieve efficient application of hydrogen energy.
