    High-density hydrogen monolayer formation and isotope diffusion in porous media
    (2019) Balderas-Xicohténcatl, Rafael; Schütz, Gisela (Prof. Dr.)
    This thesis is focused on two fundamental aspects of hydrogen physisorption. First, the density of a single layer of adsorbed hydrogen molecules is studied at temperatures close the boiling point (20 K). These systematic experiments give an explanation to high H2 monolayer capacity as a high-density phase of adsorbed hydrogen. Secondly, the diffusion of the hydrogen molecules through a porous material (ZIF-8) is studied using a commercially available adsorption apparatus. Establishing that gas adsorption experiments can be used to study hydrogen diffusion and isotope separation at temperatures close the boiling point.
