Influence of Fe3+ and F- ions on PbO2 process of electrosynthesis.

Abstract

The electrodeposition of PbO₂ on 304 stainless steel in the presence of F^- and Fe³⁺, separately or together in the growth solution, is examined.The same electrodeposition kinetics is obeyed in the absence and in the presence of Fe³⁺ and F^- in solution. Surface analysis by XRD and SEM of the Fe and F-doped PbO₂ films does not reveal major changes compared to undoped samples. The oxygen over-potentiel on Fe-F-PbO₂ electrode is higher which without Fe and F.
