The four-electron reduction of oxygen to water on a planar cobalt chelate

Abstract

In the reduction of oxygen on the planar binuclear cobalt chelate bis-(3,5-di-2-pyridyl-1,2,4-triazole)dicobalt dichloride, adsorbed on pyrolytic graphite, reduction to water occurred in alkaline solution, whereas in acid solution only hydrogen peroxide was formed; the results are compared with those for other binuclear cobalt chelates already reported.
