Abstract
Electrodes are prepared by coating electrically conductive substrates with an electrically conductive film comprising a single-metal spinel of the formula Co.sub.3 O.sub.4. The coating can include modifier oxides selected from Groups III-B through VII-B, Groups III-A through V-A, and the Lanthanides and Actinides. Particularly suitable as modifier oxides are the oxides of zirconium, vanadium, titanium, lead, tantalum, tungsten, niobium, cerium, or molybdenum. These electrodes are particularly suitable for, but not limited to, use as the anode in an electrolytic chlorine cell wherein a diaphragm is interposed between an anode and a cathode in an aqueous electrolyte solution containing sodium chloride.
