摘要：

This paper concerns the preparation of cobalt oxides through anodic deposition from Co(NO3)(2) aqueous solutions on different substrates. The electroformed oxide films exhibit good chemical stability and lower oxygen overvoltages, irrespective of the substrate material. Electrocatalytic properties are investigated through polarisation curves and impedance measurements, while the active surface area is estimated by cyclic voltammetry. Experimental data are analysed in terms of a possible reaction mechanism.
