Exploration of porous metal-oganic frameworks as promising candidate for hydrogen storage application

Porous MOFs, a new type of functional materials, hold great promise as on-board hydrogen storage media. Various strategies were explored to improve hydrogen uptakes in porous MOFs, including mimicking Hemoglobin to create entatic metal centers in PCN-9 with high hydrogen affinity of 10.1 kJ/mol, functionalizing the organic ligand with fused aromatic rings to achieve high hydrogen adsorption capacity of 2.7 wt% in PCN-14 and utilizing catenation to increase high pressure hydrogen uptake of 9.5 wt% as well as surface area of 3800 m2/g in PCN-6.
