Abstract Ti-supported PbO2 electrode doped with rare earth Er was prepared by electrodeposition method. The phase composition and microstructure of PbO2 electrodes were characterized by SEM, EDS and XRD. At the same time, EIS, VA, FP analysis and phenol degradation experiments were applied to characterize the electrodes’ electrochemical properties. Results show that the Er–PbO2 coating is mainly composed of β–PbO2; Er can decrease the particle size and increase its surface area; the fluorescent intensity of Er–PbO2 electrode is 2.3 times higher than that of PbO2 electrode. Comparing with the undoped PbO2 electrode, the Er-PbO2 electrode presents a relatively lower electrochemistry response resistance as well as a higher oxygen evolution reaction potential. Phenol degradation experiments show that Er-PbO2 electrode can enhance the electrocatalytic activity and 91.8% of phenol can be removed at 2 h.

Key words: inorganic non–metallic materials PbO2 electrode rare earth Er electro-catalysis
