The invention relates to a method for preparing a highly electrolytic hydrogen evolution active electrode. The invention aims to solve the problem of poor performance of the current non-noble metal electrolysis hydrogen catalyst. The method for preparing highly active hydrogen evolution electrode by electroless plating-forming holes on the surface of flocking steel plate: (1) preparation of activation solution; (2) preparation of plating solution; (3) preparation of pore-forming sulfurization solution; (4) chemical spraying alloy (5) Pore-forming and vulcanizing treatment, a catalytic layer with excellent hydrogen evolution reaction activity is prepared on the surface of the flocking steel plate, which is conducive to reducing the energy consumption of electrolysis of hydrogen in alkaline solution.

Description

technical field [0001] The invention belongs to the field of hydrogen-evolution electrode preparation, and relates to a method for preparing a highly active hydrogen-evolution electrode on the surface of a flocking steel plate by chemical plating-forming holes, thereby improving the activity of the hydrogen-evolution electrode. Background technique [0002] In recent years, the increasing use of fossil fuels in human life has not only caused a sharp consumption of fossil energy, but also caused huge pollution to the environment. The carbon dioxide and nitrogen oxides produced during the combustion of fossil fuels greatly increase the harmful components in the air, easily causing the greenhouse effect and acid rain. Not only that, hydrocarbons and solid particles generated by incomplete combustion of fossil fuels are one of the main reasons for the serious decline in air quality in recent years. Therefore, vigorously seeking alternatives to traditional fossil fuels can not o...
