The current status of hydrogen storage in metal–organic frameworks—updated

Hydrogen storage in metal–organic frameworks (MOFs), or porous coordination polymers, has been extensively investigated in the last two years and this review is to serve as an up to date account of the recent progress. The effects of MOF sample preparation and activation, functionalization (including post-synthetic), catenation, unsaturated metal sites, metal doping and spillover have been discussed using recent examples. In addition to a condensed reference table of all recently reported MOFs for hydrogen storage, future directions are discussed based on promising new materials and reported computational analyses.
