用气体电量计法分解极化曲线研究了温度对PbO2、Pt电极上Ce4+阳极形成过程的影响，得到了两电极上Ce4+和O2的表观活化能．在Pt电极上Ce4+的活化能大于O2的活化能；温度升高时使Ce4+的电流效率升高．但PbO2电极上Ce4+的活化能小于O2的活化能，温度升高时Ce4+的电流效率降低．研究了不同Ce3+浓度对Ti／Pt基MnO2电极上Ce4+阳极形成过程的影响，得出了该反应对［Ce3+］的表观反应级数为0．5左右；讨论了可能的机理．对比研究了不同电极材料对Ce4+的生成和O2的析出的催化性能．结果表明，石墨电极对Ce3+的阳极氧化有较好的催化活性；MnO2的催化性能很差；当MnO2与PbO2混合时，由于对O2有较大的催化作用，使Ce4+的电流效率下降．
Polarization curves were decomposed by gas-gas meter method. The effect of temperature on the formation of Ce4 + anode on PbO2 and Pt electrodes was studied. The apparent activation energies of Ce4 + and O2 at the two electrodes were obtained. The activation energy of Ce4 + is larger than that of O2 at Pt electrode. The current efficiency of Ce4 + increases with temperature. However, the activation energy of Ce4 + on PbO2 electrode is less than the activation energy of O2, and the current efficiency of Ce4 + decreases with increasing temperature. The effect of Ce3 + concentration on the formation of Ce4 + anode on Ti / Pt-based MnO2 electrode was investigated. The apparent reaction order of [Ce3 +] was about 0.5. The possible mechanism was discussed. The catalytic performance of different electrode materials for the formation of Ce4 + and the precipitation of O2 was compared. The results show that the graphite electrode has a good catalytic activity for the anodic oxidation of Ce3 +; the catalytic performance of MnO2 is very poor; when MnO2 and PbO2 are mixed, the current efficiency of Ce4 + decreases due to the greater catalytic effect on O2.
