Abstract

A sol–gel method is used to synthesize Ce–S codoped TiO2–SiO2 composite nanocrystalline films on the glass substrates in this paper. The influence of the metal/nonmetal ions codoping on both the physicochemical characteristics and photocatalytic performance of the composite film was studied. It was found that ions codoping induces a better charge separation and a smaller band gap energy, which are responsible for the improvement in the photo-degradation with respect to the acid naphthol red aqueous solution under visible light illumination. Moreover, the morphology, crystalline structures and compositions of the films were analyzed, and the doping mechanism was also investigated.
