The behavior of prepared films was described by means of their functional, photocatalytic and photo-induced electrochemical properties. The TiO2 and M/TiO2 (M=Ag, Zr, Fe) thin films were prepared via the sol-gel method using titanium n-butoxide, acetylacetone and transition metal acetylacetonates as precursors. Prepared films were then analyzed by a series of characterization techniques involving XRD, Raman spectroscopy, SEM, AFM and XPS. The photocatalytic activity of prepared films was monitored by the decomposition rate of Rhodamine B in water. All films were also tested for their photo-induced electrochemical properties based on evaluation of polarization curves (photocurrents). The differences among these properties were discussed for all prepared thin films.
