对β-PbO2电化学臭氧生成的几个方面进行了研究。电极材料的形态用广泛的(总的，外部的)原位测定。如果有合适的电极表征参数，可以与其他实验室的结果进行比较。用准静态极化曲线、逐点极化和计时电位法研究了支持电解液性质对析氧反应(OER)/EOP过程的影响。采用表观比功率准则对几种β-PbO2/电解液体系的性能进行了评价。提出了一种详细的EOP机制。
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.
