Abstract

Cobalt deposits taking the form of cobalt nodules were obtained on nickel substrates in a bath containing dissolved cobalt sulphate and ammonium citrate at pH 9.8 and 23-degrees-C. Oxygen discharge was investigated on those electrodes in 40 wt % KOH solution at temperatures ranging between 40 and 80-degrees-C. Up to a cobalt loading of 12 mg cm-2,the larger the loading, the larger the electrode/solution interface, which resulted in improved electrocatalytic activity with the loading. The electrocatalytic activity was also largely temperature-dependent.
