Hexagonal-disk-shaped Mg NCs (magnesium nanocrystals) have been fabricated within a porous MOF (metal–organic framework). In their Communication on page 9814 ff, M. P. Suh et al. report on the adsorption of hydrogen gas by Mg NCs@MOF both by physi- and chemisorption. Compared to pristine MOF, Mg NCs@MOF increases isosteric heat and uptake capacities of H2 physisorption, and decreases chemisorption/desorption temperatures by 200 K compared to bare Mg powder.
