Preparation and Characterization of PbO2 Electrode Modified with Praseodymium


Article Preview

The Ti/PbO2 electrode doped with Pr2O3 was prepared by the electrodeposition method. The X-ray diffraction (XRD) analyses indicated the crystal particles size of Ti/PbO2/Pr2O3 electrode was diminished due to the incorporation of Pr2O3 into the film of PbO2. The scanning electronic microscopy (SEM) revealed that Ti/PbO2/Pr2O3 electrode had smaller particles and larger active surface. The measurement of cyclic voltammograms (CV) revealed Ti/PbO2/Pr2O3 electrode had a better electrochemical properties comparing to Ti/PbO2 electrode. The bulk electrolysis demonstrated that the Ti/PbO2/Pr2O3 electrode presented excellent electrocatalytic performance for degradation methylene blue.
