Synthesis of ordered mesoporous silicas SBA-15 materials Functionalized with high loading of amine groups by a one-pot route
有机基团功能化的有序介孔二氧化硅材料因其广泛的应用前景而备受关注。材料表面的有机官能团杂化是决定材料应用价值的关键因素，得到有序性好，有机基团修饰率高且分布均一的是现今研究的重点。本文中以非离子表面活性剂P123为模板剂，正硅酸乙酯作为硅源，在酸性条件下，通过与3-氨丙基三甲氧基硅烷缩合，一步法（共嫁接法）合成修饰率高，材料有序性好的介孔二氧化硅材料SBA-15，并通过XRD、FTIR和29Si 固态核磁对其进行表征，结果表明材料保持了较好的孔道有序性和高的官能化修饰率。
Functionalization of mesoporous silica materials with organic groups has opened new possibilities for their various applications. Since the content of organic groups is a key factor that determines many important properties of the hybrid materials, synthesis of ordered mesoporous materials with a high content of organic functional groups uniformly distributed over the ordered structure is highly desirable. In this paper, Ordered SBA-15 functionalized with a high loading of pendant amine groups has been synthesized via co-condensation of tetraethoxysilane (TEOS) and 3-aminopropytrimethoxysilane (APTMS) templated by Pluronic P123 under acidic conditions. and the resulting functionalized materials were characterized by XRD, FTIR and 29Si MAS NMR, the result indicated that the material was ordered, and with high loading of amine groups.
