Method for using anodes having NiCo.sub.2 O.sub.4 catalyst for the electrolysis of potassium hydroxide solutions and method of making an anode containing NiCo.sub.2 O.sub.4 catalyst

摘要

Anodes having NiCo.sub.2 O.sub.4 catalyst used in the electrolysis of water to produce hydrogen and oxygen result in anode voltage requirements of less than about 1500 millivolts at 100 milliamperes per square centimeter of anode area. Typically, oxygen evolving anodes comprised of lead or carbon steel are utilized in the electrolysis of water to produce oxygen resulting in high voltage requirements. Anodes containing NiCo.sub. 2 O.sub.4 catalyst require substantially reduced voltages and perform well in the conventional alkaline electrochemical production environment.
