Acidic Character and Catalytic Activity of Sulpho-Functionalized Porous Silica with an Ordered Structure

Acidic Character and Catalytic Activity of Sulpho-Functionalized Porous Silica with an Ordered Structure

Microporous organosilica incorporating various amounts of sulpho groups (MS-SO 3 H) was prepared by hydrolysis and the co-condensation of tetramethoxysilane (TMOS) and mercaptopropyl trimethoxysilane (MPTMS), followed by oxidation of the thiol group. The resulting microporous silica had a regular po...
