摘要：

A novel visible-light-active C-N-Cl-codoped TiO2 photocatalyst was prepared by a simple process. The as-prepared sample was characterized by XRD, XPS, and UV-Vis. The analysis results showed that the as-synthesized sample was anatase and possessed a narrow bad gap of 2.4 eV after the doping of carbon, nitrogen and chlorine. An obvious absorption for visible light was observed in the range of 400 similar to 700 nm for C-N-Cl-codoped TiO2. By degrading of methyl orange (MO) solution under the visible light (lambda>420 nm) irradiation, the synthesized photocatalyst showed 5 times photocatalytic activity than that of P25.
