Hydrogen storage mechanisms in disordered nanoporous carbons
In this proposal, we plan to investigate the low-pressure (0-1 bar) physisorption behavior of hydrogen (H2), deuterium (D2) and a zero scattering length density H2/D2 mixture under cryogenic temperatures (77-100 K) in three disordered carbon systems with different hierarchical pore structures. This will be done by in-situ Small-Angle Neutron Scattering (SANS) at D22 or D16 combined with a gas sorption analyzer provided by the ILL. SANS is considered one of the most effective techniques to study in detail the arrangement of guest atoms, molecules or ions in a confined nanopore space. The contrast variation experiment will allow us to separate local contrast effects and pore volume changes. The SANS data will be analyzed by classical models while real space structure models will be also developed. The aim of this study is to gain a deeper understanding of the basic H2 adsorption and storage mechanisms in nanoporous carbons, thus providing guidelines on the tailoring of the carbon pore structure towards optimized H2 storage properties for mobile and stationary CO2-free applications.
