Description	The interaction between molecular hydrogen and the alkali-metal-exchanged zeolites Na-FER and K-FER at a low temperature was investigated by combining variable-temperature infrared spectroscopy and theoretical calculations using a periodic DFT model. The adsorption enthalpies of H2 on alkali-metal exchanged FER are significantly smaller than those found previously for the MFI-type zeolites Na-ZSM-5 and K-ZSM-5; which is likely due to a difference in the alkali-metal-cation coordination in the two zeolite frameworks.

(en) Interakce molekulárního vodíku s mimomřížkovými kationty alkalických kovů v zeolitech Na-FER a K-FER byla studována za nízkých teplot pomocí VTIR spektroskopie v kombinaci s výpočty provedenými s periodickým DFT modelem. Nalezené adsorbční enthalpie H2 na alkalických centrech ve FER jsou výrazně menší než enthalpie nalezené pro zeolity Na-ZSM-5 a K-ZSM-5. Rozdílné enthlapie jsou způsobeny rozdíly v koordinaci alkalických kationtů v zeolitech FER a ZSM-5. (cs)
