Abstract
PURPOSE: To produce cathode described in the title of low hydrogen overvoltage, by electro-plating of metallic cathode substrate by use of composite iron plating bath, which contains an additive selected from inorg. flocculants, polymeric flocculants, and surface active agents, and which contains Fe3O4 powder diffused in the bath.
CONSTITUTION: At least a portion of a metallic cathode substrate, made of iron, stainless steel, nickel, or platinum group metal is electrolyzed by use of a plating bath of composite iron bath, pref., ferrous chloride bath, which contains an additive selected from inorg. flocculants (e.g., aluminum chloride, sodium metasilicate, etc.), cationic, or nonionic, polymeric flocculants (e.g., dextrin, starch, poly-2- diethylaminooxyethyl metacrylate), cationic, or nonionic, surface active agents (e.g., polyoxyethylene alkylamine), and which contains diffused Fe3O4 powder, in order to manufacture a cathode for use in electrolysis of aq. alkali metal halogenide soln. Electrolyte is of pH 3W6, and of Fe2+ conc. 0.2W1.5 mol/l, pref. 0.5W 1.0 mol/l, and contains no NH+ 4.
