摘要

PbO_x films were prepared under various deposition conditions. The exact stoichiometries of these films were determined by titration. These PbO_x electrodes were used for oxygen evolution in aqueous perchloric acid solution and the influence of nonstoichiometry of PbO_x films on their electrochemical activity was investigated.
