Organic Structure Directing Agent-Free and Seed-Induced Synthesis of Enriched Intracrystal Mesoporous ZSM-5 Zeolite for Shape-Selective Reaction.

Sowing the seeds: A sub‐micron single‐crystal‐like ZSM‐5 catalyst with enriched intracrystal mesopores is synthesized through a facile organic structure‐directing agent‐free and seed‐induced route. The special crystal structure leads to significantly improved catalytic activity, well‐preserved shape selectivity, and slow deactivation in the isomerization of o‐xylene to p‐xylene.
