Cellular solid composite containing metal nanoparticles, preparation method and use for reversible storage of hydrogen

摘要

A macroporous monolithic composite material to a carbon monolith is provided having a hierarchized porous structure has metal nanoparticles. The arrangement also includes a process for the preparation thereof, a process for storing hydrogen that uses same, and to a process for producing gaseous hydrogen that uses such a composite material, where the process is reversible.
