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

doi:10.3724/SP.J.1077.2007.01065

Abstract

Abstract: 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.

Key words: cerium-doped TiO₂/Ti photoelectrodes, anodization, visible light, photoelectrocatalytic
