The electrosynthesis of ozone at ambient temperature can be achieved using anodes (preferably PbO2) in aqueous, buffered electrolytes (neutral to slightly acidic media). Traces of highly adsorbing anions raise the oxygen overpotential and the O3 yield, whilst anions with a high charge/radius ratio as well as certain transition metal ions have detrimental effects. Ozone is evolved at high electrode potentials despite corrosion of the (PbO2, Pt or Au) anode. The same is true in general, when competing electrooxidations occur (e.g. with ClO3-). At fixed temperature and current density the 03 yield at a PbO2 anode decreases when the pressure is raised from 1 to 10 atm. |
