Preparation method of sponge-structured alloy ternary oxide layer-loaded hydrogen evolution electrode material

Abstract

The invention provides a preparation method of a sponge-structured alloy ternary oxide layer-loaded hydrogen evolution electrode material. The preparation method specifically comprises the following preparation processes: a process of electrically depositing an organic solvent of a La-Y base layer of a sponge structure, a process of electrically depositing a Ni-Cu middle layer on the surface of the La-Y base layer, a process of electrically compositing and depositing Ni-Cu and RuO2 particles on the surface of the Ni-Cu middle layer, a process of performing atomic diffusion treatment, and a process of anodizing a sponge-structured Ni-Cu-La-Y alloy base body-loaded RuO2 layer. The novel hydrogen evolution electrode material prepared by the preparation method disclosed by the invention is high in chemical stability and electrocatalytic activity, has excellent low hydrogen evolution overpotential and high specific surface area, and can be applied to large-scale industrial production for preparing hydrogen by low-energy-consumption water electrolysis.

Description

technical field [0001] The invention relates to the field of hydrogen evolution electrode materials, in particular to a sponge structure Ni-Cu-La-Y alloy loaded with CuO / NiO / RuO 2 A method for preparing a hydrogen evolution electrode material with a ternary oxide layer. Background technique [0002] The importance of energy and the environment in social and economic development has become increasingly prominent; so far, fossil fuels provide more than 80% of human energy, and the use of fossil fuels not only seriously pollutes the environment, but also its reserves are increasingly depleted. As an efficient and clean energy source, hydrogen has been paid more and more attention. Water electrolysis reaction is an effective way to achieve large-scale industrial production of hydrogen, and reducing the overpotential of hydrogen evolution is the core technology to reduce the energy consumption of hydrogen production by electrolysis of water. Nickel alloys have significant electr...
