| Abstract: | Mesoporous titanosilicates with MFI structure were prepared by assembling from TS-1 nanocluster with mesoporous carbon as the hard-templates.The characterization results show that the sample is of 2D hexagonal ordered mesostructure with MFI micro-structure in the framework.Additionally,SEM images confirm the existence of macropores.Such titanosilicate shows a high catalytic activity in epoxidation of cyclohexene.This mesoporous TS-1 sample would have widely potential applications in industry because of the combining advantages of microporous TS-1(high catalytic activities) and mesoporous materials(mesoporous channels). |
