Abstract

Amino and ether organic group were successfully grafted into the pore of MCM41 mesoporous sieve,with γaminopropyltriethoxy silane and γglycidoxypropyltrimethoxy silane as the coupling agent.The inorganic/organic composite mesoporous materials NH2(CH2)3MCM41 and CH2OCHCH2O(CH2)3MCM41 were synthesized,and characterized by XRD,nitrogen adsorptiondesorption,elemental analysis and FTIR.The results of the characterization show that amino and ether not only get into the modified inner wall,but also remain the ordered mesoporou structure of MCM41.
