Abstract
In order to improve the performance of PbO2electrode, A kind of surface active agent – AEO-7 was added into nitric acid bath and modified PbO2electrode was prepared on stainless steel substrate by anodic oxidation. The modified variations on surface morphology of the electrodes were examined by Scanning Electron Microscopy(SEM); The polarization curves, Tafel curves and Cyclic voltammograms of modified and unmodified PbO2electrodes were compared in Crystal violet solution; The electrocatalytic activities were inspected by electrocatalytic degradation of crystal violet. It was found that the modified electrode showed higher oxygen evolution potential, better corrosion resistance, and more excellent electrocatalytic activity than the unmodified electrode.
