摘要：

Hierarchically nanoporous ZSM-5 with micropores and mesopores was successfully one-pot synthesized through a dual-template using tetrapropylammonium hydroxide and poly(ethylene oxide) as microporous and mesoporous templates, respectively. Hierarchically nanoporous ZSM-5 was characterized by X-ray diffraction (XRD), nitrogen adsorption, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The influence of poly(ethylene oxide) on hierarchically nanoporous properties of the sample was investigated. Hierarchically nanoporous ZSM-5 showed higher activity in catalytic cracking of 1,3,5-tri-isopropylbenzene than conventional ZSM-5 which is synthesized in the absence of poly(ethylene oxide).
