摘要: 在温和条件下,以3-氨丙基三乙氧基硅烷为偶联剂,修饰介孔分子筛 MCM-41(Si/Al=35),成功地将有机官能团引入到介孔分子筛孔道中,制备了一种无机一有机复合材料MCM-(CHNH,以 XRD、FTIR、DTA-TGA、 N吸附-脱附和 HREM表征了复合材料;结果表明:有机基团-(CHNH不仅进人孔道、修饰了MCM-41的孔壁,而且使介孔分子筛MCM-41保持了有序的孔道结构.

Abstract: Under mild experiomental conditions, with 3-aminopropyltriethoxysilane as the coupling agent, mesoporous molacular sieve MCM--41(Si/Al=35) was modified,
and --(CH2)_3NH2 organic functional group was successfully introduced into the pore of the mesoporous sieve, the organic/inorganic complex material MCM--(CH2)3NH2
was synthesized, and characterized by XRD, FTIR, DTA-TG, nitrogen adsorption-desorption at 77K and HREM. The results of the characterization show that --(CH2)3NH2
not only gets into the modified inner wall of mesoporous MCM-41, but also makes MCM--41 remain its ordered pore structure.

Key words: MCM--41, modified, 3-aminopropyltriethoxysilane, MCM-(CH2)3NH2
