•A simple method has been developed to produce hierarchically nanoporous ZSM-5.•The sample showed hierarchical porosity and large pore volume.•The sample showed higher catalytic activity than conventional ZSM-5 in cracking.
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).
Graphical abstractHierarchically nanoporous ZSM-5 has been successfully one-pot synthesized through a dual-template using tetrapropylammonium hydroxide and poly(ethylene oxide) as templates, respectively. The SEM image shows there are some hierarchically nanoporous in this sample.Figure optionsDownload full-size imageDownload as PowerPoint slide
