【要旨】
Proton-exchanged Y zeolite (H?Y zeolite) has two types of bridging hydroxyl groups; one exists in the supercage and the other exists in the sodalitecage. The dynamic property of protons due to these hydroxyl groups was investigated by variable temperature 1H magic-angle spinning nuclear magnetic resonance (1H MAS NMR). Proton exchange between two types due to these hydroxyl groups proceeded at temperatures higher than ca. 500 K. The temperature dependence of the spectra was explained using the McCornell equation. The activation energy of the proton exchange was estimated to be 50 kJ mol?1.
