Abstract: TiO2/WO3 and WO3/TiO2 bilayered films were deposited onto glass substrates by DC reactive magnetron sputtering and their photocatalytic activity was evaluated on the decolorization of Rhodamine 6G (Rh6G) aqueous solutions. The structures, morphologies and optical properties of TiO2 and WO3 layers and also of the bilayered films were studied by X-ray diffraction, field emission scanning electron microscopy and UV-Vis spectroscopy. It was found that the bilayered films exhibit good adherence to the substrates and high mechanic stability. The structural characterization revealed that in both nanocomposites independently of the above layer, the main phase observed in the X-ray patterns corresponds to WO3 and the optical properties are similar to the WO3 layer. The photocatalytic efficiency of the nanocrystalline bilayered films was further compared with TiO2 and WO3 films also produced by sputtering and the results show that the higher photocatalytic activity was achieved by the bilayere d film with WO3 as the upper layer.
