Abstract

SBA-15 mesoporous organosilicas with the p6m symmetry were synthesized by sol-gel co-condensation of tetraethyl orthosilicate with mercaptopropyltriethoxysilane, bis[3-(ethoxysilyl)propyl]ethane, bis[3-(ethoxy-silyl) propyl]disulfide, and bis[3-(ethoxysilyl)propyl]tetrasulfide. Final samples were characterized by X-ray diffraction and nitrogen sorption measurements. Depending on the monomers used, the resulted materials exhibit well or poorly ordered structures. All materials have a well-developed porous structure and high chapter of sulfur-containing moieties introduced by co-condensation.
