摘　　要：采用水玻璃为硅源、三氯化钛为钛源,在四丙基氢氧化铵(TAPOH)和阳离子聚合物共模板的条件下,成功地合成了介孔TS-1沸石。采用X-射线衍射、N2-物理吸附、扫描电镜、透射电镜、红外光谱和紫外光谱对合成的介孔TS-1沸石进行了表征。结果表明,合成的样品具有很好的结晶度和良好的四配位骨架Ti,并且沸石晶体内存在丰富的介孔结构。对大分子二苯基硫醚和二苄基硫醚的氧化实验结果显示,与微孔TS-1相比,含有介孔的TS-1沸石具有更好的催化性能。Using water glass and TIC13 as silicon and titanium sources, the mesoporous zeolite TS-1 was successfully synthesized with the help of cooperative template of TPAOH and cation polymer. Then the mesoporous zeolite TS-1 was characterized by X-xay diffraction, N2 physical adsorption, SEM, TEM,FT-IR and UV-Vis spectral. The synthesized mesoporous TS-1 show high crystallization and well planted Ti and abundant mesostmcture in the crystal; and it show high catalytic activity in oxidation ofbulldy moleculers such as diphenyl sulfide and dibvnzyl sulfide, compared with microvorous TS-1.
