Improved Hydrogen Storage in the Metal‐Organic Framework Cu3(BTC)2

A new pressure‐free synthesis method was developed producing the porous material Cu 3 (BTC) 2 (BTC = benzene tricarboxylate) with a very high micropore volume up to 0.62 cm 3 g –1 . The compound is a promising nanoporous solid for adsorptive hydrogen storage under cryogenic conditions with a capacity of 2.18 wt% which is higher than that of IRMOFs and other coordination polymers.
