  • HYDROGEN STORAGE WITH GRAPHITE ANION INTERCALATION COMPOUNDS
    Publication number: 20080175780
    Abstract: The disclosure relates to a material for reversibly storing and releasing hydrogen comprising graphite or a graphitic structure, for example, comprising an ordered graphite structure of carbon and nitrogen atoms wherein the interlayer and/or interstitial volume is occupied with at least one intercalated anionic species. While any suitable anionic species can be employed, examples of suitable species are at least one of: F? (fluoride), (C?C)2? (diacetylide), and (N?C?N)2?. Desirable anionic species typically have a relatively high charge to volume ratio. The disclosure also relates to a material for reversibly storing and releasing hydrogen comprising ordered graphitic structures comprising at least one member selected from the group of graphite, single walled carbon nanotubes, multiwalled carbon nanotubes, graphite nanofibers, carbon nanohorns, and boron nitride.
