Synthesis, Characterization and Photocatalytic Activity of AgCl Loaded on TiO₂/SBA-15 Composites

Abstract

TiO2/SBA-15 and AgCl loaded on TiO2/SBA-15(AgCl-TiO2/SBA-15) composites were synthesized by a facile method. All products were characterized by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and N2adsorption-desorption analysis. Photocatalytic activities of the composites were assessed by the photocatalytic decomposition of methyl orange (MO). The results indicated that TiO2or TiO2-AgCl existed in the matrix SBA-15, which reduced the specific surface area, pore volume and pore size of the matrix. The photocatalytic performances of TiO2/SBA-15 were higher than that of pure TiO2, and the resultant AgCl-TiO2/SBA-15 composites showed much higher photocatalytic performances than TiO2/SBA-15.
