Ordered mesoporous silica of SBA-15 type was modified with 3-(trihydroxysilyl)-1-propanesulfonic acid (TPS) in order to obtain a solid acid catalyst. The structure and surface properties of the materials obtained were compared with those of SBA-15 si

Mesoporous silica of the SBA-15 type was used as a support for basic active centers generated by the incorporation of calcium species and (3-aminopropylo)trimethoxysilane (APTMS) or imidazole. The samples were characterized by low temperature N2 adso
