A novel PbO2 electrode doped with rare earth of Nd (Nd-PbO2) was prepared by electrodepositon technique. The microstructure and electrochemical properties of the doped electrode were investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), fluorospectrophotometry (FP), Linear-sweep voltammetry (LSV), accelerated lifetime (ALT) and cyclic voltammetry (CV). SEM, XRD and XPS analysis reveal that the Nd-PbO2 electrode is covered by β-PbO2 with tetragonal crystal structure and the main chemical valence of Nd is 3 , and the morphology and elementary composition of the electrode surface have changed at different degrees. Electrochemical performance tests show that doping with Nd can increase oxygen evolution reaction and stability of PbO2 electrode. The results of CV and AOII degradation experiments indicate that Nd-PbO2 electrode can enhance the direct anodic oxidation, which is helpful to mineralize AOII. Besides, the FP analysis reveals that the electrocatalytic activity of the Nd-PbO2 electrode in the degradation of organic materials is higher than that of the PbO2 electrode because more hydroxyl radicals can be generated on its surface.
