【Abstract】 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.更多还原
