摘要
M41S、HMS、MSU和SBA等具有规则孔道结构的介孔硅基分子筛及其杂原子衍生物在多相催化、吸附分离及材料科学领域有重要的学术研究与工程应用价值。此类物质可以通过长链季铵盐、伯胺、双子胺或聚氧乙烯类表面活性剂胶束的模板作用,在多种不同的条件下合成,并可通过SEM、TEM、XRD、N2(Ar)等温吸附-脱附技术和FT-IR、激光Raman、固体MASNMR、UV-Vis漫反射、XPS、EXAFS、XANES等谱学手段加以表征。本文对介孔硅基分子筛近年来所取得的进展进行了综述。
The M41S, HMS, MSU, and SBA silica based crystalline mesoporous molecular sieves are of great academic and practical importance in catalysis, absorptive separation technology, and materials science. Such materials may be prepared by involving the micellae of long chain quaternary ammonium ion, primary amine, geminal amine, or polyethylene oxide surfactants as templating species, and characterized by SEM, TEM, XRD, N 2 (Ar) adsorption desorption techniques, FT IR, laser Raman, solid state MAS NMR, UV Vis diffuse reflectance, XPS, EXAFS, and XANES spectroscopy. In this review, progress made in these aspects are summarized.
