Molecular dynamics simulations of H-2 at 243 K in NU-100, UiO-68, and IRMOF-16 with zero, one, three, and six Mg alkoxide functional groups per linker were performed, revealing interesting behavior of the Maxwell-Stefan (M-S) diffusivity in these systems. A strong relationship between the isosteric heat of adsorption and the M-S diffusivity was found, with the M-S diffusivity decreasing exponentially with increasing heat of adsorption. The insights obtained may be valuable for future studies of diffusion and gas storage in nanoporous materials with strongly interacting functional groups.
