摘要
近年来,多级结构钛硅分子筛(TS-1)引起了越来越多的关注。本文综述了多级结构钛硅分子筛制备研究的最新进展,介绍了不同的制备方法和先进表征技术,并比较了各制备方法的优劣势,讨论了合成材料的孔结构、活性钛物种对烯烃环氧化催化反应和燃油催化氧化脱硫性能的影响。最后,对多级结构钛硅分子筛面临的挑战和未来的发展前景进行了展望。
Hierarchical titanosilicate-1(TS-1)zeolites have received increasing attention owing to their abundant micro/meso/macro-porous structures and superior catalytic properties.In this paper,recent advances on synthesis,characterization and catalytic performance of hierarchical TS-1 zeolites was reviewed.Firstly,various synthesis protocols were introduced,and the advantages and disadvantages of each of them were compared.Secondly,advanced characterization techniques,especially electron tomography(ET)and solid ^(17)O NMR,were present.Thirdly,the catalytic properties of resultant materials on olefins epoxidation and oxidation desulfurization of fuels were discussed.Finally,the challenges and future development of hierarchical TS-1 zeolites were proposed.
