Description
Summary:Electrochemical oxidation is an efficient and pollution-free technology that belongs to the advanced oxidation process. The anode with excellent characteristics is a key factor that affects the electrocatalytic oxidation system. To explore the difference of performance between the PbO 2 electrode and RuO 2 -IrO 2 electrode, the morphology, microstructure, and other electrochemical properties were tested respectively. The scanning electron microscopy (SEM) shows that the PbO 2 film is a typical pyramid shape with a compact structure while many cracks appear on RuO 2 -IrO 2 film. The PbO 2 and RuO 2 -IrO 2 crystallize sizes are 22.7 nm and 31.3 nm, respectively. The oxygen evolution overpotential of the PbO 2 electrode is 1.33 V (vs. SCE) a little lower than the RuO 2 -IrO 2 electrode of 1.41 V (vs. SCE). The phenol and crystal violet (CV) are applied as the target contaminants to check the electrocatalytic performance of the two electrodes. The experiment results show that the RuO 2 -IrO 2 electrode is fit for the degradation of crystal violet and the PbO 2 electrode is fit for the degradation of phenol. The better electrocatalytic performance on the degradation of crystal violet by RuO 2 -IrO 2 electrode can be attributed to the higher oxygen evolution overpotential.
