A hierarchical zeolite MFI has been synthesised and investigated for its potential feasibility in SF6/N2 separation. Zeolite MFI possessing a hierarchical microporous–mesoporous structure (MFI-2) displayed an enhanced SF6/N2 selectivity at 40 °C as compared to bulk MFI (MFI-1). More importantly, at...
