Hydrogen storage in metal-organic frameworks

Metal-organic frameworks (MOFs) are a new class of crystalline materials consisting of metal ions linked together by organic ligands, resulting in a highly microporous network. Owing to their high specific surface area and tailored pore dimensions, MOFs are ideal materials for hydrogen storage based on physisorption. This review gives an overview on the progress achieved in the field of hydrogen adsorption in MOFs. Advantages over other classes of porous materials as well as limits of MOFs are also discussed.
