سنتز و بررسي خواص نانو ذرات تيتانيا به همراه افزودني همزمان كاتيونهاي Sn و W

In this study, preparation of Sn and W co-doped TiO2 nonopowder by TBT, SnCl2.2H2O and Na2WO4.2H2O as precursor via sol-gel process invistigated. The effects of W content and Sn on the stractural, optical, and photo-catalytic properties of applied nonopowder have been studied by x-ray diffraction(XRD), scanning electron microscopy (SEM). XRD pattern showed an decrease in peak intensities of the Anatase crystalline phase by increasing the W and Sn co-doped. The prepared W and Sn co-doped TiO2 photo-catalyst nanopowder showed optical absorption edge in the visibile light area and exhibited xcellent photo-catalytic abblity for degredation of methylene Blue solution under Vis irradiation. The result showes that doping an appropriate amount of W and Sn can effectivity improve the photo-catalytic activity of TiO2 nanopowder
