摘要：

Several aspects of electrochemical ozone production (EOP) on beta-PbO2 were investigated. The morphology of the electrode material was determined in situ using extensive ( total., external. and internal differential capacity) and intensive parameters (the morphology factor, phi) permitting comparison with results of other laboratories if appropriate electrode characterization parameters are available. The influence of the nature of the supporting electrolyte on the oxygen evolution reaction (OER)/EOP processes was investigated using polarization curves, recorded under quasi-stationary conditions, point-by-point polarization, and chronopotentiometry. The performance of the several beta-PbO2/electrolyte system was evaluated using the apparent specific power criterion. A detailed mechanism for EOP is proposed.
