H2 adsorption and ortho-para conversion on ETS-10

摘要：

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.
