Ethylenediamino and 2, 4-pentanedione-functionalized mesoporous molecular sieves were achieved by modfication of mesoporous HMS or MCM- 41. The homogeneous Mo02(acac)2 species was first heterogenized onto the organically functionalized mesoporous molecular sieves, resulting in the hybrid catalysts for cyclohexene epoxidation. The developed catalysts exhibited as high activity as their homogeneous one for cyclohexene epoxidation, and the selectivity was up to 80%
