ABSTRACT:
Disclosed herein is a cathode having an electroconductive substrate and a porous surface. The porous surface is characterized by containing a major portion of nickel and a hydrogen overvoltage reducing amount of molybdenum. The molybdenum may be present as elemental molybdenum, as an alloy with nickel, or as a molybdenum compound. Also disclosed is an electrolytic cell having an anode, a cathode, and a separator between the anode and cathode, where the cathode is characterized by a porous surface having a major portion of nickel and a hydrogen over voltage reducing amount of molybdenum, which molybdenum may be present as elemental molybdenum, and molybdenum alloy with nickel or a molybdenum compound.
Further disclosed is a method of electrolyzing an alkali metal chloride brine by passing an electrical current from an anode to a cathode to evolve chlorine at the anode and hydroxyl ion at the cathode. The cathode is characterized by a porous surface containing a major portion of nickel and hydrogen overvoltage reducing amount of molybdenum.
Also disclosed is a method of preparing a porous nickel electrode by flame spraying nickel bearing particles, leachable constituent bearing particles and molybdenum bearing particles onto a metal substrate and leaching out the leachable constituent whereby to form the porous surface.
