Abstract: The preparation of functionalized mesoporous molecular sieves were introduced, which are including the formation of the acid active sites, redox active sites and used the support for immsobilizing enzyme catalysts by heteroatomic substitution; the formation of polymerization active sites, acid active sites or chiral catalysis sites by the organic－inorganic graft (or hybridization); as the carriers, the transition metals, transition metal oxides and acid catalysts are supported. The progresses on the preparation and catalytic activities of the functionalized mesoporous molecular sieves are reviewed.
