Abstract

Hierarchical zeolites offer improved mass transfer and catalytic performance, yet their controlled synthesis remains challenging. We report a one-pot synthesis of size-tunable, rod-shaped aligned ZSM-5 (RA-ZSM-5) using tetraethylammonium and tetrabutylammonium hydroxides. The crystallization mechanism and improved mass diffusion associated with the hierarchical structure are elucidated.
