摘　　要：Mesoporous stannosilicate molecular sieves with MCM-48 structure have been synthesized by hydrothermal 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 mesoporous MCM-48. The prepared SnMCM-48 exhibits catalytic performance different from Sn/MCM-48 prepared by impregnation in phenol hydroxylation.Mesoporous stannosilicate molecular sieves with MCM-48 structure have been synthesized by hydrothermal method and characterized by elemental analysis, XRD, N2 adsorption, UV-Visible, and FTIR.
