沿S0I0路径,以十六胺为模板剂,以3-氨丙基三乙氧基硅烷为有机硅源,通过与TEOS共水解沉淀合成了氨丙基官能化HMS介孔分子筛.采用粉末X-射线衍射分析、N2吸/脱附、扫描电镜分析、高分辨透射电镜分析、傅立叶变换红外分析以及元素分析等表征手段,对所合成的材料进行表征.氨丙基官能化HMS介孔分子筛具有worm-like孔道结构,且较为均一的孔径分布.研究了前体硅源中3-氨丙基三乙氧基硅烷含量的变化对氨丙基官能化HMS介孔分子筛的相结构及织构性能的影响.傅立叶变换红外分析表明,NH2-CH2-CH2-CH2有机基团分布在杂化HMS介孔孔道中.
Amino propyl functional HMS mesoporous molecular sieves were synthesized by hydrolytic precipitation with TEOS using hexadecylamine as template and 3-aminopropyltriethoxysilane as organic silicon source along the path of S0I0. Ray diffraction analysis, N2 adsorption / desorption, scanning electron microscopy analysis, high-resolution transmission electron microscopy, Fourier transform infrared spectroscopy and elemental analysis characterization of the synthesized material.The aminopropyl functional HMS mesoporous molecular sieve worm -like pore structure, and a more uniform pore size distribution.Studies on the changes of the content of 3-aminopropyltriethoxysilane in precursor silicon source for the phase structure and texture properties of aminopropyl functional HMS mesoporous molecular sieves The Fourier transform infrared spectroscopy showed that the NH2-CH2-CH2-CH2 organic groups were distributed in the hybrid HMS mesopores.
