Abstract: The effect of the additives, which were added in the solution for preparing the PbO2 anode, on the performance of the anodic ozone evolution on the PbO2 electrode has been studied. The results show that halide and transition metal ions have an influence on the performance and morphology of deposited PbO2 film on the iron electrode. The activity and stability of the PbO2 anode for ozone evolution were significantly improved, when both chloride ion and ferric ion were used as the additives. A nonporous lead dioxide film on the iron plate has been thus prepared.

Key words: Ozone, Anode, Lead dioxide
