Smooth, compact, and bright films of nickel and cobalt oxides were prepared from 0.5M acetate aqueous solutions and electrodeposited onto platinum and graphite electrodes. Oxygen evolution potentials in 1M NaOH at room temperature were about 150-170 mV lower on nickel (III) oxide (NiO(OH)) and cobalt (III) oxide (Co/sub 2/ O/sub 3/)-coated anodes than on bare anodes. Scanning electron micrographs of NiO(OH) deposits showed no morphological change after extensive electrolysis, and electrocatalytic activity was stable in long-term controlled-potential coulometric electrolysis. However, the electrocatalytic activity of Co/sub 2/O/sub 3/ showed initial decay followed by a fairly constant behavior. No visible change in the surface of the Co/sub 2/O/sub 3/ deposit was observed after extensive electrolysis.
