摘要: Hydrogen storage by physisorption is a very promising technique due to its fast kinetics and full reversibility. The key reach high capacities specific surface area. Extremely large areas can only be achieved materials with porosity, i.e., nanosponges like MOF-177 (4239 m2 g−1) DUT-23(Co) (4850 g−1). Even of more than 6000 g−1 have been recently reported in the literature these new hydrogen excess uptakes up 9 wt% at 77 K. Within novel class metal–organic frameworks (MOFs), crystalline synthesized well-defined pore structure inner exceeding best activated carbons. An overview given on adsorption desorption measurements performed mainly our laboratory. focus this paper lies progress understanding structure–property relationship nanosponges. Furthermore, technologically relevant parameters as total usable are introduced.
