Preparation of Cerium-doped TiO_2/Ti Photoelectrodes and Photoelectrocatalytic Performance under Visible Light

Sun Hai

Abstract

Cerium-doped TiO_2/Ti photoelectrodes were prepared by anodization.The photoelectrodes were characterized by SEM,XRD,XRF,XPS and UV/VIS/NIR,and their photoelectrocatalytic perfor- mance under visible light irradiation was also investigated.Taking degradation efficiency of rhodamine B as indication,the preparing conditions of Cerium-doped TiO_2/Ti photoelectrodes were optimized.The optimal parameters are voltage of 160V,current density of 100mA/cm~2 and Ce(NO_3)_3 concentration of 960 mg/L.
