Three methods were used to synthesize sulfur-functionalized silica materials with spherical morphology: (a) impregnation of CS2 and S-8 onto preformed silica support (MCM-TEOS); (b) co-condensation of TEOS and BTESPT/MPTMS; and (c) direct use of BTESPT and MPTMS as precursors. The presence of sulfur...
