The present invention relates to an electrode, a method for its use in electrolysis. …<??>The electrode according to the invention comprises a metallic substrate having a porous catalytic surface. In one embodiment of the invention the electrode is prepared by providing a pair of spaced apart wires, at least one of the wires comprising a catalytic metal and at least one of the wires comprising a leachable metal, establishing an electrical potential between the wires whereby to establish an arc therebetween and melt a portion of each of the wires, depositing molten material on the substrate, and removing the leachable metal. …<??>By the use of an electrode according to the invention as the cathode in an electrolytic cell, it has been found that the hydrogen overvoltage may be reduced to from about 0.01 volt to about 0.10 volt. |
