Abstract

Adsorption of H₂ at 20 K on (Na,K) ETS-10 is studied by means of infrared spectroscopy and molecular mechanics simulations. The occurrence of three steps is evidenced, consisting of: (i) specific interaction of H₂ with extraframework cations; (ii) aspecific interaction with the channel walls and (iii) pore-filling by a liquid-like phase. Spectroscopic evidence is also given that (Na,K) ETS-10 promotes ortho-para conversion of the adsorbed H₂ species.
