The influence of nonstoichiometry on the electrocatalytic activity of PbO2 for oxygen evolution in acidic media

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