Localization, structure and dynamics of physisorbed H2 on the surface and in pores of gels used as precursor for smectite clay synthesis
Up to now all the research on H2 adsorption have been focused on crystalline materials having well define pore structure closely matching the H2 kinetic diameter (e.g. MOFs, zeolite, nanotubes and carbon nanofibers). We have recently revealed a surprisingly high H2 uptake by gels used as precursors for hydrothermal synthesis of smectites: hectorite and saponite. The gels are by definition amorphous, but they display a high surface area (about 4 to 5 times higher than their well crystallized clay equivalent), and high volume of micropores. This proposal aims at understanding how H2 behave in the nanostructure of these gels, what is its localization and dynamic in the structure. Based on this understanding, we hope to improve the sorption properties of the gels, in order to make them a low-cost material for large-scale, land-based H2 storage applications.
