摘要: 利用介孔碳作硬模板合成出具有MFI骨架结构的介孔钛硅材料. 该样品复制了类似SBA-15的介孔结构, 同时骨架含有MFI微孔结构. 透射电镜表征结果表明, 样品表面还有部分大孔结构. 催化结果证明了该样品既具有介孔材料较大孔道结构, 又保持了微孔钛硅材料的高活性.

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).

Key words: Titanosilicate, Mesoporous material, TS-1, Catalytic oxidation
