摘要

Metal-organic frameworks (MOFs) are nanoporous materials researchers are investigating as storage media for hydrogen fuel. MOF-5 comprises 1,4-benzenedicarboxylate linkers joining Zn_4O clusters in a cubic system. Previous work has shown that MOF-5 can store 1.3 wt% of hydrogen at 78 K and ≈1 atm. Andreas Blomqvist et al. report calculations showing that the adsorption of lithium atoms on the organic linkers would greatly increase the amount of hydrogen that MOF-5 can store.
