Synthesis and Characterization of Photocatalytic Material TiO2/SBA-15

TiO2/SBA-15 materials have been synthesized via a simple indirect hydrothermal method under weak acidic conditions. The powder was characterized by X-ray diffraction (XRD), N2 adsorption-desorption, Fourier transformed infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The synthetic products showed highly ordered mesoporous structure with uniform pore sizes, speci c surface areas SBET of 133 m2/g and 256 m2/g at the TiO2:SiO2 mass ratios of 75:25 and 50:50, respectively. The photocatalytic activity of these materials has been studied by methylene blue decomposition under UV light irradiation.
