    This study demonstrates the preparation of thin nanoparticulate films of titanium dioxide and transition metal ions doped titanium dioxide. 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.
