چکیده
TiO2, ZrO2 nanoparticles and TiO2/ZrO2 nanocomposite were prepared by co-precipitation method. The structure and physicochemical properties of samples were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), UV-vis absorption spectrophotometer. The results show that TiO2/ZrO2 nanocomposites are composed of mainly titania and tetragonal ZrO2. The photocatalytic reactions confirmed that the nanocomposite sample showed better photocatalytic activity than ZrO2 and TiO2 samples. The diffuse reflectance UV-vis Spectra of the binary oxides have been shifted to shorter wavelengths with increasing ZrO2 molar ratio. This study represents example of attempt to prepare a new potential photoactive mixed oxide system, containing two ions (Ti4+ and Zr4+) with good photcatalytic activity compare with commercial TiO2 calcined at 450°C.
