The present invention relates to the storage of hydrogen in layered nanostructures possessing: at least some crystallinity, interstices from about 0.335 nm to 0.67 nm, and chemisorption properties with respect to hydrogen at those surfaces of the nanostructure which define the interstices. Preferred layered nanostructures are carbon nanostructures such as those selected form carbon nanotubes, carbon fibrils, carbon nanoshells, and carbon nanofibers. Hydrogen is chemisorbed into the interstices of the nanotructures.

L'invention concerne le stockage de l'hydrogène dans des nanostructures en couches possédant au moins une certaine cristallinité, des interstices compris entre 0,335 et 0,67 nm et des propriétés de chimisorption par rapport à l'hydrogène au niveau des surfaces de la nanostructure qui définissent les interstices. Les nanostructures en couches préférées sont des nanostructures de carbone telles que celles sélectionnées parmi les nanotubes, les fibrilles, le nanocoques et les nanofibres de carbone. L'hydrogène subit un processus de chimisorption dans les interstices des nanostructures.
