TiO2 and TiO2/ZnO films with silver nanoparticles (Ag NP’s) distributed in the matrix and on the surface were characterized by TEM, AFM and UV-Vis spectroscopy. Direct photoelectrochemical investigations of the TiO2/Ag and TiO2/ZnO/Ag heterojunctions showed the cathodic shift of the flat-band potential position and the increase of photocurrent quantum yield in comparison with unmodified TiO2 electrodes. Photocatalytic activity of Ag/TiO2 and Ag/ TiO2/ZnO films estimated in the process of Rhodamine B dye degradation is coincides with photoelectrochemical data.
