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--有机?复合材料MCM-(CH2)3NH2.以XRD、FTIR、DTA--TGA、N2吸附-脱附和HREM?表征了复合材料,结果表明:有机基团-(CH2)3NH2不仅进入?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.
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
