Preparation of Novel TiO{sub}2/Ti Photoelectrode and Photoelectrocatalytic Degradation of Rhodamine B

摘要

A novel dye-sensitied TiO{sub}2/Ti photoelectrode was firstly prepared by anodization process and then was filmed with composite poly(vinyl alcohol) on surface. The photoelectrodes were characterized by atomic force microscopy (AFM) and X-ray diffraction (XRD). The photoelectrocatalytic degradation of Rhodamine B (Rh B) was performed under visible light irradiation on these photoelectrocatalysts. It was found that Rh B were degraded completely after 2h using the novel dye-sensitied TiO{sub}2/Ti photoelectrode under visible light.
