Metal oxides have attracted most attention in semiconducting technology because of their high transparency in the visible spectrum and low electrical resistivity [1,3]. We deposited the pure and tin (Sn) doped CdO films using ultrasonic spray pyrolysis (USP) technique with Sn concentrations of 1, 2 and 3%. The aims of this study how different doping ratio affects the photocatalytic activity of CdO nanostructured films. The prepared samples were characterized by X-ray diffraction (XRD) and UV-Vis spectroscopy techniques. XRD patterns of the samples showed their cubic structure with the crystallite size in the range of 17.1 and 26.8 nm. Their photocatalytic activities were investigated by photocatalytic degradation of methylene blue under UV radiation. The effects of operational parameters such as photo catalyst load and initial concentration of the dye on photocatalytic degradation of methylene blue were evaluated. The presence of the tin within the range of 1% to 3% in the CdO film affects to the photo catalytic performance of the films. It has been declared that the photocatalytic properties of nanostructured CdO films are successfully modified/controlled by tin doping.
