Hydrogen Storage in Porous Materials: Status, Milestones, and Challenges

Hydrogen storage in porous materials, current status and future challenges

Hydrogen storage in porous materials gained considerable interest, since in the past 15 years many new coordination polymers or framework materials have been synthesized, which show a permanent ultra-high porosity and an extremely large specific surface area [1-3]. Different classes of these novel highly porous structures, e.g., metal-organic frameworks (MOFs), zeolitic imidazolate frameworks (...

Hydrogen Storage by Physisorption on Porous Materials

Characterisation of porous hydrogen storage materials: carbons, zeolites, MOFs and PIMs.

Porous materials adsorb H2 through physisorption, a process which typically has a rather low enthalpy of adsorption (e.g. ca. 4 to 7 kJ mol(-1) for MOFs), thus requiring cryogenic temperatures for hydrogen storage. In this paper, we consider some of the issues associated with the accurate characterisation of the hydrogen adsorption properties of microporous materials. We present comparative gra...

Preparation and hydrogen storage capacity of highly porous activated carbon materials derived from polythiophene

Highly porous carbons have been successfully synthesized by chemical activation of polythiophene with KOH. The activation process was performed under relatively mild activation conditions, i. e., a KOH/polymer weight ratio of 2 and reaction temperatures in the 600 – 850 oC range. The porous carbons thus obtained possess very large surface areas, up to 3000 m/g, and pore volumes of up to 1.75 cm...
