| 摘 要： | 自M41S问世以来1],其在吸附、催化及催化剂载体等领域的应用成为人们研究的热点。但纯硅M41S本身不具有催化活性中心,不能直接应用于催化反应中,将具有催化活性的金属掺杂在分子筛骨架中是赋予M41S系列介孔分子筛催化性能的重要手段。文献2,3]已报道了一些金属掺杂在MCM-41中

| Abstract: | 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. |
