Identification of distinct Bronsted acidic sites in zeolite mordenite by proton localization and [Al-27]-H-1 REAPDOR NMR
Résumé
[27Al]-1H REAPDOR (Rotational Echo Adiabatic Passage DOuble Resonance) NMR experiments distinguish structurally dissimilar Brønsted acid sites located in main 8 and 12 membered-ring channels of the zeolite mordenite.
