Abstract

The invention discloses a preparation method of a foam electrode for water electrolysis, which belongs to the technical field of water electrolysis. Foam nickel is selected as the base material of the electrode material; oil stains on the surface of the foam nickel are removed so that the surface is clean; the foam nickel is soaked in diluted acid solution, and the surface of the foam nickel is activated; pure water is used to flush the activated foam nickel, and the foam nickel is quickly soaked into an electrodeposition tank as a cathode for electrodeposition; the active surface is prepared; the foam electrode with the active surface is thoroughly cleaned, dried and thermally treated; and the thermally treated foam material is cut to prepare the electrode material. The high-activity foam electrode material prepared through the method provided by the invention can be used for the electrode material in the electrolysis hydrogen production industry, can reduce hydrogen precipitation overpotential in the electrolysis process, reduce energy consumption, and improve the production efficiency.

Description

technical field

[0001] The invention belongs to the technical field of water electrolysis, in particular to a method for preparing a foam electrode for water electrolysis. Background technique

[0002] Hydrogen is a very important industrial gas species, which is widely used in chemical industry, energy, electronics, metallurgy, food, machinery, aerospace, nuclear industry and many other fields. For example, in chemical industries such as synthetic ammonia and methanol, the supply and production costs of hydrogen directly determine the production costs of these basic materials and affect the development of the entire industry. Hydrogen, as a clean energy, has attracted more and more attention, and its demand is gradually increasing.

[0003] Hydrogen production by electrolysis of water is one of the important methods for producing hydrogen. The process principle is to use two electrodes that do not react chemically, and when a direct current is conducted with an aqueous sol...
