Bayberry-like ZnO/MFI zeolite as high performance methanol-to-aromatics catalyst

Abstract

Unique bayberry-like MFI zeolites are synthesized through a quasi-solid-state crystallization approach. This hierarchical zeolite structure has a relatively thick shell, densely grown nanocrystals with an ordered packed channel, high mechanical stability, high surface area and a low Si/Al ratio. Its catalytic efficiency for methanol-to-aromatics is significantly higher than that of conventional MFI zeolites.
