Abstract
Periodic mesoporous organosilicas (PMO) functionalized with sulfonic acid group have been successfully synthesized by co-condensation of bis(triethoxysily)ethane and 3- mercaptopropyltrimethoxysilane in the presence of octadecyltrimethylammonium chloride as the structure-directing agent under basic conditions. The PMO materials have been characterized by nitrogen adsorption, powder X-ray diffraction, IR, and thermogravimetric analysis. The results indicate that the materials exhibit well-ordered mesostructures, high surface areas and solid acid properties.
