Metal-organic frameworks (MOFs) are due to their extremely high porosity and defined structure very attractive materials for hydrogen storage at cryogenic temperatures (77 K). The storage capacity of molecular hydrogen in MOFs is higher than for any other porous material and further improvements are expected if the framework structure of novel MOFs will be optimized. This optimization can involve different routes like increasing the specific surface area, tuning the size of the pores and introducing metal centers which might strongly polarize the molecule. This presentation will give an overview on the most important results obtained in the last years on hydrogen storage in MOFs focusing on the correlation between structure and hydrogen adsorption properties. Additionally, a comparison between MOFs and other classes of porous materials for hydrogen physisorption will be presented. Finally several experimental techniques will be shown which allow to investigate the interaction between hydrogen and metal-organic frameworks.
