Abstract

Abstract : A unique bayberry-shaped MFI zeolite structure with a zeolite shell (1–1.5 μm in thickness) and numerous zeolite nanowires (500–800 nm in length) vertically grown on two sides of the shell is prepared. The catalytic efficiency is significantly higher than that of the conventional ZnO/MFI zeolite. 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.
