Antibacterial Behavior of Ag-Ce-TiO2 Composite Films in the Different Irradiations

摘要：

An Ag-Ce-TiO2 composite film was prepared by incorporating Ag in the Ce-TiO2 films with an impregnation method through photoreduction. The bactericidal activity of the Ag-Ce-TiO2 composite film and the effect of deposition of silver and doping cerium in the different irradiations on the antibacterial performance were assessed against Escherichia coli (E. coli). It was found that the Ag-Ce-TiO2 composite film was composed of predominant anatase titania, cerium oxides (in the form of Ce2O3/CeO2) and silver nanoparticles. The Ag-Ce-TiO2 composite film has much higher antibacterial efficiency than glass and pure TiO2 film either in the room light or in the dark.
