Immobilization of catalysts on the surface of some inert supports makes therecovering step easier. Because of the specific physicochemical properties, zeolites are good candidate as catalyst supports. In this study, zeolite X was synthesized by natural kaolin and TiO2 was incorporated into zeolite phase by impregnation method. Degradation of Safranin Orange, methylene blue and 2,4–dinitroaniline […]
In this study, the dissociative adsorption of NaNO2, NaNO3, HNO2, HNO3 and H2SO4 over (1 1 0) surface of γ-alumina non-spinel model were investigated through the dispersion corrected density functional theory (DFT-D) at PBE-D/DNP level of calculation. It was found that all of the species are dissociated to their ionic forms after adsorption and relaxation […]
Both metal oxides, ceria (CeO2) and stania (SnO2) are prepared by precipitation technique using ammonia solution (1:1) and characterized by thermogravimetric analysis (TGA), x-ray powder diffraction (XRD), transmission electron microscope (TEM), nitrogen adsorption-desorption (for the specific surface area determination, SBET) and used in the photodegradation of Tenoxicam (TEN) antibiotics by using ultraviolet irradiation in presence […]
