N2 - One intriguing possibility to combat the dwindling world-wide supply of petroleum along with associated environmental challenges, is to use hydrogen as the energy carrier. However, there is still not a suitable hydrogen storage material. The synthesis of nano-porous materials with extremely large surface areas, including metal-organic frameworks (MOFs) and amorphous carbons, has led to some progress in understanding the adsorption of hydrogen molecules on material surfaces. However there are still many technological obstacles to their future deployment: 1) The low H2 adsorption enthalpy limits their application to low temperature; and 2) The lack of understanding of surface packing density (SPD) hinders the efficient improvement of H2 uptake. We will illustrate the diverse range of hydrogen adsorption properties of MOFs aimed at addressing these two issues. Additionally, through the use of neutron diffraction, neutron spectroscopy and isotherm measurements, we will illustrate the intrinsic framework flexibility in MIL-53 through the temperature and pressure response of the framework and relate this to the large amplitude breathing effect common in these materials.
