摘要: 采用阳极氧化法制备铈掺杂TiO2/Ti光电极, 用SEM、XRD、XRF、XPS和UV/VIS/NIR对光电极的性能进行表征, 并对其可见光照射下的光电催化性能进行了测试. 研究结果表明:在成膜电压为160V, 电流密度为100mA/cm2, Ce(NO3)3浓度为960mg/L条件下制备的铈掺杂TiO2/Ti光电极在降解罗丹明B的实验中表现出良好的光电催化活性.

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
