摘要：Hierarchical TS-1 has been synthesized in the presence of cationic organosilane surfactant. The material is characterized with XRD, TEM, N(2) adsorption isotherm. The results show that the hierarchical TS-1 aggregates consist of small primary units with sizes of 20-30 nm. The BET surface area increases from 420 to 513 m(2)/g compared to conventional TS-1 zeolite. The sample is shown to be more active in epoxidation of cyclohexene than conventional TS-1.
