Achieving High Density of Adsorbed Hydrogen in Microporous Metal Organic Frameworks

Two microporous metal organic framework structures are shown to possess hydrogen uptake capacities reaching 1.74 and 1.98 wt.‐% at 77 K (1, 2, see Figure). These give the highest adsorbed H2 density reported thus far for metal‐organic‐based porous materials. The estimated pore volumes are 0.33 and 0...

Summary:Two microporous metal organic framework structures are shown to possess hydrogen uptake capacities reaching 1.74 and 1.98 wt.‐% at 77 K (1, 2, see Figure). These give the highest adsorbed H2 density reported thus far for metal‐organic‐based porous materials. The estimated pore volumes are 0.33 and 0.38 cm3 g–1 for 1 and 2.
