XRD, nitrogen adsorption and TEM show that the product has a highly ordered structure and the hexagonal arrangements of uniformly size pores distribution.展开更多
The β CD was first successfully introduced into the pore of MCM 41 mesoporous sieve, with γ glycidoxypr opyltrimethoxy silane (GPTS) as a coupling agent.

An inorganic/organic complex mesoporous material β CD MCM 41 was synthesized, and characterized by XRD, nitrogen adsorption desorption, elemental analysis, FT IR and spectrophotofluorimetry. The results show that β CD molecular not only get into the modified inner wall, but also remain the ordered mesoporou structure of MCM 41.展开更多
