Title
Controllable synthesis of chainlike hierarchical ZSM-5 templated by sucrose and its catalytic performance
Abstract

•Chainlike hierarchical ZSM-5 was synthesized by using sucrose as the template.•Chainlike morphology is stacked with several submicron zeolite crystals.•Chain length and pore structures of ZSM-5 can be tuned by added amount of sucrose.•Chainlike ZSM-5 exhibited higher conversion and 2,6-dimethylnaphthalene yield.

Hierarchical ZSM-5 with controllable chainlike structure was hydrothermally synthesized with sucrose as template, characterized by XRD, FT-IR, N2 adsorption, SEM and TEM, and used for methylation of 2-methylnaphthalene. Hierarchical ZSM-5 can be rapidly synthesized, and chainlike morphology is stacked with several submicron crystals. With increasing sucrose amount in the precursor, the chain structure became more obvious, and the surface area and pore volume of mesopores increased. Narrow mesoporous distribution was centered at about 7 nm. It is thought that the formation of mesopores is related to the template role of sucrose. Chainlike hierarchical ZSM-5 exhibited high 2-methylnaphthalene conversion and 2,6-dimethylnaphthalene yield.
