A hierarchical bulky ZSM-5 zeolite synthesized via glycerol-mediated crystallization using a mesoporous steam-treated dry gel as the precursor†
Abstract
Glycerol-mediated crystallization transforms a steam-treated dry gel used as the mesoporous precursor into a hierarchical ZSM-5 zeolite. The hierarchical ZSM-5 zeolite with auxiliary mesoporosity and acidity exhibits higher activity in the aldol condensation reaction of benzaldehyde with n-butyl alcohol.
