Positive Effect

In this study, WO3/TiO2nanotube array photoelectrodes were fabricated by anodic oxidation and electro-deposition method. The effects of WO3, H2O2, oxygen, and pH value were investigated in the degradation of Dimethyl phthalate (DMP). Results show that the photocatalytic property of the photoelectrode was improved by the modification of WO3. The degradation rate of DMP was increased by 9.3% after 120min irradiation. H2O2could significantly promote the degradation of DMP. The degradation rate of DMP was increased by 27.9% and arrived 97.5% after 120 min irradiation. A certain amount of O2added to the solution had positive effect on the degradation of DMP. While excessive O2would undermine the degradation. The degradation rate of DMP was improved in both acidic condition and alkaline condition. It was separately increased by 38.4% and 40.2% at the pH value of 3.0 and 7.0, compared with that of pH = 7.
