Abstract

The invention discloses an electrolyzed water catalyst applicable to a full pH range and a preparation method thereof, and the preparation method comprises the following steps: firstly, preparing a copper-nickel organic complex through solvothermal, and then calcining the complex in an inert atmosphere to obtain a carbon-oxygen functional group modified non-noble metal CuNiCo-coated C=O alloy electrocatalyst. The catalyst has high HER activity in a neutral environment and a whole pH range, greatly reduces the cost, and is more suitable for industrial mass production.

Description

technical field [0001] The invention relates to the technical field of electrolytic water catalysts, in particular to an electrolytic water catalyst suitable for all pH ranges and a preparation method thereof. Background technique [0002] With the aggravation of energy crisis and environmental pollution, it is imminent to find renewable energy and clean energy to replace traditional fossil fuels. Hydrogen has been listed as a national strategic new energy due to its rich sources, high combustion value, low density, multiple available forms, pollution-free, and storable properties. Hydrogen can be produced from renewable energy such as hydropower, wind energy, solar energy, and biomass energy, as well as coal, natural gas, and secondary energy electricity. Hydrogen can be used in traditional fields and new transportation vehicles, as well as hydrogen power generation. The hydrogen industry chain can be divided into three parts: upstream hydrogen production, midstream stora...
