摘要：

Al/alpha-PbO2/beta-PbO2 composite electrodes doped with rare earth oxide (CeO2) were prepared by anodic oxidation method investigate the influence of nano-CeO2 dopants on the properties of Al/alpha-PbO2/beta-PbO2-CeO2 electrodes and the impact of alpha-PbO2 as the intermediate layer. The results show that using alpha-PbO2 as the intermediate layer will benefit the crystallization of beta-PbO2 and beta-PbO2 is more suitable as the surface layer than alpha-PbO2. CeO2 dopants change the crystallite size and crystal structure, enhance the catalytic activity, and even change the deposition mechanism of PbO2. The doping of CeO2 in the PbO2 electrodes can enhance the electro-catalytic activity, which is helpful for oxygen evolution, and therefore reduce the cell voltage.
