Thermal and Kinetic Performance of Water Desorption for N2 Adsorption in Li-LSX Zeolite

“…In the case of water−cation interactions, it is evident that the interactions between higher electropositive cations and the unshared electron pair of the oxygen atom in water are very strong. 41 Therefore, Li-LSX shows a greater extent of water interaction as compared to the Na-LSX zeolite, whereas a hydrogen bond could be formed between the nearest framework oxygen and one of the hydrogens of the water molecule. As a result, the water−oxygen interactions in Li-LSX are more favorable than those in Na-LSX zeolite, while the required temperature for completing the desorption of water depends on all of the water interactions, which in turn primarily relies on the size and distribution of nonframework cations.…”

“…According to Joshi et al, performance of the nonframework cations plays a key role in the governance of water–cation, water–water, and water–oxygen interactions. In the case of water–cation interactions, it is evident that the interactions between higher electropositive cations and the unshared electron pair of the oxygen atom in water are very strong . Therefore, Li-LSX shows a greater extent of water interaction as compared to the Na-LSX zeolite, whereas a hydrogen bond could be formed between the nearest framework oxygen and one of the hydrogens of the water molecule.…”
