Anodes having NiCo.sub.2 O.sub.4 catalyst used in the electrohydrodimerization of acrylonitrile to adiponitrile result in anode voltage requirements of less than about 2000 millivolts at 100 milliamperes per square centimeter of anode area. Typically, oxygen evolving anodes comprised of lead or carbon...http://www.google.com.au/patents/US4596638?utm_source=gb-gplus-sharePatent US4596638 - Method for the electrochemical production of adiponitrile using anodes having NiCo.sub.2 O.sub.4 catalyst
