摘　　要：含锡介孔分子筛MCM-48用水热合成法合成，运用远素分析法，XRD，N2吸附，紫外可见光和红外光谱分析进行表征。结果表明，Sn能嵌入介孔分子筛MCM-48四面体晶格点阵中。水热合成的SnMCM-48在苯酚羟基化方面展示了与浸渍法制得的负载型Sn／MCM-48不同的催化性能。Mesoporous stannoosilicate molecular sieves with MCM -48 structure have been synthe- sized by hy - drothermal method and characterized by elemental analysis, XRD, N2 adsorption, UV - Visible, and FTIR, The results show that Sn in the synthesis gel can be incorporated into the tetrahedral lattice site of mesopourous MCM - 48. The prepared Sn MCM - 48 exhibits catalytic performance different from Sn/MCM -48 prepared by impregnation in phenol hydroxylation.
