This paper describes the development of nanostructured thin films of Ag-TiO2 by the Mw-glycol irradiation of silver ions on TiO2 thin films prepared by sol–gel spin-coating (SGS) methods. Where the effect of silver containing TiO2 nanoparticles were tested in photocatalytic applications. For increasing the photocatalytic activity was related to associate effects: the electron transfer from TiO2 to Ag, reducing the electron–hole recombination, thickness of the film and silver distribution. From the experimental results without surfactant Ag-TiO2 films exhibited much better photoactivity than the surfactant (PEG-2000) Ag-TiO2 films due to excess of silver composition this has been explained in terms of SEM morphology and EDX Analysis.
