【 摘 要 】

A systematic examination of the cryogenic H2 adsorption properties below critical point of H2 (Tc = 33 K) on various kind of adsorbents was carried out, then the density of adsorbed H2 on each adsorbent and its temperature dependence were experimentally compared with the liquid H2. Usually, H2 adsorption capacities on porous materials were investigated at liquid nitrogen temperature (77 K) to realize its practical application for H2 storage and most of reports have focused on the development of new porous materials. On the other hand, the density of adsorbed H2 below critical point of H2 was investigated for metal -organic frameworks, super-activated carbon, and graphene nanoplatelets in this study. We found the superdense H2 adsorption as the monolayer state, having much higher density than liquid H2.(c) 2022 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
