Abstract

We examine the hydrogen adsorption behavior of chabazite (CHA) and Linde Type A (LTA) zeolites, both of which possess an eight-membered ring (Si₈O₈), as the temperature was increased from 77 K (thermal adsorption spectroscopy). The CHA-type zeolites started to uptake hydrogen at around 200 K, whereas no other adsorbent showed any hydrogen uptake. The hydrogen adsorption temperature of CHA was similar to that observed by thermal desorption spectroscopy. A high D₂/H₂ separation ability at relatively high temperature in the CHA-type zeolites may be expected in the intrinsic adsorption property.
