Figure 1. (A) Simulated XRD pattern (bottom) of KFI and experimental XRD pattern (top); (B) SEM image; and (C) TG curve of KFI-5.4 zeolite (synthesis condition: 150 °C, 5 days); (D) 13C liquid NMR spectrum (bottom) of (K+)CCH and 13C solid-state MAS NMR spectrum (top) of KFI-5.4 zeolite; (E) 27Al and (F) 29Si solid-state MAS NMR spectra of KFI-5.4 zeolite. XRD: X-ray diffractometer; SEM: scanning electron microscope; TG: thermogravimetric analysis; NMR: nuclear magnetic resonance; MAS: magic angle spinning.
