Preparation of SnO<sub>2</sub>-TiO<sub>2</sub>/Zeolite Y Composites with Enhanced Photocatalytic Activity
Abstract
SnO 2 -TiO 2 /zeolite Y composites were prepared by the impregnation of tin chloride and tetrabutyl titanate solution with zeolite Y and subsequent calcination at 500. SnO 2 -TiO 2 heterostructures coated on zeolite Y is ascertained by X-ray diffraction, high-resolution transmission electron microscopy and UV-vis diffuse reflectance spectra characterization. The photocatalytic studies suggested that the SnO 2 -TiO 2 /zeolite Y showed enhanced photocatalytic efficiency of photodegradation of methyl orange compared with TiO 2 / zeolite Y and SnO 2 /zeolite Y under UV light irradiation.
