Preparation of Cerium-doped TiO2/Ti Photoelectrodes and Photoelectrocatalytic Performance under Visible Light

Cerium-doped TiO2/Ti photoelectrodes were prepared by anodization. The photoelectrodes were characterized by SEM, XRD, XRF, XPS and UV/VIS/NIR, and their photoelectrocatalytic performance under visible light irradiation was also investigated. Taking degradation efficiency of rhodamine B as indication, the preparing conditions of Cerium-doped TiO2/Ti photoelectrodes were optimized. The optimal parameters are voltage of 160V, current density of 100mA/c 2 and Ce(NO3)3 concentration of 960 mg/L.
