Investigation of pseudo-condensation of supercritical H2 in nanoporous hydrogen storage materials studied via small angle neutron scattering

DOI

This proposal aims to use small angle neutron scattering for characterization of hydrogen adsorption (including the provision of a quantitative value for the absolute hydrogen density) in nanoporous hydrogen storage materials at cryogenic temperatures and high pressures. We will collect SANS spectra from three well-characterised carbide-derived carbon materials having systematically increasing pore diameters at 77 K to obtain a direct measure of the densities of H2 adsorbed as a function of in-situ gas dosing pressure (up to 50 bar). In addition, we will use H/D contrast matching to obtain information on the mobility of the condensed phase. Finally, to ascertain whether adsorptive H2 densification is primarily a result of confinement or whether surface interactions play a significant role, the density of the hydrogen in a very high uptake MOF material will be measured.
