摘要

A tetrahydro-salen copper(n)complex(1)is grafted on the iodosilane modified surfaces of MCM-41 and MCM-48.The presence of complex 1 on the surfaces is evidenced by ~1H MAS-NMR,elemental analysis and TG-MS.The strucutre of the supports after modification remains intact,which is evident from powder XRD,N_2 adsorption/desorption(BET),and TEM analysis.The grafted materials are applicable as catalysts for cyclooctene epoxidation and they are found to maintain activity for several runs.
