摘　　要：用Al2(SO4)3对中孔分子筛MCM-41进行改性,制备了中孔分子筛Al/SO24-/MCM-41.采用X射线多晶衍射(XRD)、红外光谱(FT-IR)、N2吸附-脱附和NH3程序升温脱附(NH3-TPD)等测试技术对样品的结构和表面酸性进行了表征.结果表明,用Al2(SO4)3改性中孔分子筛MCM-41,能得到仍保持着六方介孔结构的中孔分子筛Al/SO24-/MCM-41.The Al/SO2-4/MCM-41 were prepared by modifying MCM-41 with Al2（SO4）3.The structures and surface acidity of Al/SO2-4/MCM-41 were characterized by X-ray diffraction（XRD）,Fourier transform infrared spectroscopy（FT-IR）,N2 adsorption-desorption and NH3 temperature programmed desorption（NH3-TPD）.The results showed that the mesoporous molecular sieves Al/SO2-4/MCM-41 keeping up their hexagonal mesoporous structure can be obtained by modifying MCM-41 with Al2（SO4）3.
