Adsorption of gas molecules is a typical application for zeolites. Interaction of adsorbed molecules with cations in zeolite frameworks is responsible for selectivity and adsorption strength. Through detailed analysis of the cation distribution in zeolite Y containing Na+, Ba2+, and Ru3+ cations by NMR and X-ray diffraction combined with adsorption studies it was possible to develop a reversible, highly performant NOx adsorbent. The results demonstrate intimate understanding of guest–host interactions can lead to rational tailoring of zeolite properties.
