| 中文摘要: |
| 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. |
| 英文摘要: |
| Aminopropyl-incorporated HMS silica materials were synthesized by a "one-pot" co-condensation from tetraethylorthosilicate(TEOS) and aminopropyltriethoxysilane(APTES) using hexadecylamine as the structure-directing species via the " S0I0" route.The synthesized materials were characterized by means of X-ray diffraction,N2 adsorption,SEM,HRTEM,FT-IR,and element analysis.Mesoporous phases with worm-like channels as well as uniformpores can be prepared via the " S0I0" route.The variations of the phase structure and texture properties with the content of APTES were studied.FT-IR analysis revealed that the aminopropyl group remains intact in the channels of the hybrid HMS silicas. |
