Nano-crystallite oriented self-assembled ZSM-5 zeolite and its LDPE cracking properties: Effects of accessibility and strength of acid sites.

Highlights: [•] Nano-crystallite oriented-assembled ZSM-5 zeolite is prepared by seed-induced route. [•] Morphology and external surface are regulated by co-effects of KF, template, and seed. [•] Crystallinity and intrinsic acidity are preserved when decreasing crystallite size. [•] Fine accessibility and high acid strength lead to notable LDPE cracking activity. [•] Fast and low-cost preparation opens a possibility for large-scale production. [ABSTRACT FROM AUTHOR]
