Unstable-Fe-site-induced formation of mesopores in microporous zeolite Y without using organic templates

Author affiliations

Abstract

A novel organic template-free strategy for generating mesoporosity in Y zeolites is reported. It is revealed that Fe3+ functioned as unstable sites in the Fe–NaY zeolite, which promotes deferrization–dealumination, leading to enhanced formation of intra-crystalline mesopores as well as desirable interconnectivity. The mesopore-enriched zeolite exhibits a remarkable ability in conversion of the bulky substrate.
