In this paper, Ag-doped TiO2 thin films with nano-crystal have been prepared by the sol-gel processing. Annealing method was chosen under air and vaccum atmosphere respectively. The results indicate that the annealing atmosphere has influences on the structures and photocatalytic degradation of dye solution by thin films. The photocatalytic activities of Ag-TiO2 and TiO2 films annealed under air atmosphere were higher than that of annealed under vaccum atmosphere. Meanwhile, the photocatalytic activities of TiO2 thin film could be increased when a moderate Ag was doped.
