Propylsulfonic acid functionalized cubic mesoporous silica was fabricated through in situ oxidization of mercaptopropyl groups with H2O2 during co-condensation of tetraethyl orthosilicate and 3-mercaptopropyl trimethoxysilane under strong acidic conditions. The materials obtained with 5-20 mol % loadings of sulfonic acid groups had surface areas of up to 1300 m2/g and pore sizes of ca. 2.5 nm. The catalytic activity of this material was investigated: tests were performed on the esterification of palmitic acid being a model compound in the process of biodiesel production. Methyl ester yield on this new nanoporous catalyst is very remarkable during a mild liquid phase reaction.
