ABSTRACT:
A novel cathode for use in electrolysis of an aqueous solution of an alkali metal halide or water is provided which comprises a metallic cathode substrate and a powder of Raney nickel held on its surface partly embedded in a nickel layer deposited thereon from a nickel plating bath. The cathode has a considerably lower hydrogen overvoltage than ordinary cathodes. It can be produced by electrolytically depositing nickel on the surface of a metallic cathode substrate from an aqueous nickel plating bath containing a powder of Raney nickel suspended therein to form a co-deposited layer of the nickel and the Raney nickel powder.
