Abstract:

An improved hydrogen evolution cathode with a conductive metal core and an integral Raney-type catalytic surface predominantly derived from an adherent ternary aluminide Beta structured intermetallic crystalline precursory outer portion of the metal core is disclosed. The precursory outer portion preferably has molybdenum added to give a percursor alloy having the formula Ni. sub. x Mo. sub. y Al. sub. 3 where x is within the range of from about 80 to about 95 weight percent and y is within the range of from about 5 to about 20 weight percent of the Ni-Mo portion of the alloy. Also disclosed is a method of producing a low overvoltage cathode. The method includes the steps of taking a Ni-Mo core or substrate having about 5-20 weight percentage of Mo and coating it with aluminum, heat treating to form a Ni--Mo--Al ternary alloy with mostly NiAl. sub. 3 (ordered orthorhombic) crystal structure and then leaching out the Al to produce a binary NiMo alloy Raney surface. A method for utilizing said low overvoltage cathode for producing hydrogen and an exemplary cell for so doing are also disclosed.
