The electrochemical performances of Co(3)O(4) nanopowders, obtained by the sol-gel method, were investigated and compared with those of commercial Co(3)O(4) powders, for oxygen evolution reaction in alkaline solution. The active oxide powder was mixed with teflon and assembled on Ti substrate to form thin catalyst film. Cyclic voltammetry, polarization curves, and electrochemical impedance spectroscopy were used to assess the mechanism of oxygen evolution reaction, chemical structure, and morphology of the catalyst.
