ELECTRODE BASE, NEGATIVE ELECTRODE FOR AQUEOUS SOLUTION ELECTROLYSIS USING SAME, METHOD FOR PRODUCING THE ELECTRODE BASE, AND METHOD FOR PRODUCING THE NEGATIVE ELECTRODE FOR AQUEOUS SOLUTION ELECTROLYSIS

摘要

Disclosed is a negative electrode for aqueous solution electrolysis, which comprises: a conductive base that has a nickel surface; a mixture layer that is formed on the surface of the conductive base and contains nickel metal, nickel oxide and carbon atoms; and an electrode catalyst layer that is formed on the surface of the mixture layer. The electrode catalyst layer is configured of a layer that contains a platinum group metal or a compound of a platinum group metal. The negative electrode for aqueous solution electrolysis is suitable for electrolysis of an aqueous solution of an alkali metal halide.
