| 摘 要： | 利用直接合成法和后接枝法将含有磺酸基团的硅烷偶联剂引入MCM-41介孔分子筛中, 合成了酸性介孔有机-无机杂化材料. 利用XRD和TEM等方法对其结构进行了表征. 结果表明,利用直接合成法和后接枝法合成的杂化材料仍保持规整的介孔孔道,该材料作为酸催化剂在苯甲醛与乙二醇的缩醛反应中显示了较好的催化活性.

| Abstract: | Mesoporous MCM-41 materials, which were first synthesized by researchers at Mobil Corporation in 1992, have a uniform hexagonal array of mesopores with high surface area, adjustable pore size and high thermal stability. However, pure silica MCM-41 has low acidity and is not a good catalyst. In the last decade, much effort has been put into increasing the acidity of pure silica MCM-41 by introducing metal species~ , sulfated metal oxides~ and heteropolyacids~ . |
