HYDROGEN STORAGE MATERIAL AND METHODS OF PRODUCING AND UTILIZING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen storage material having excellent hydrogen storage ability and being easily produced, and to provide methods of producing and utilizing the same. SOLUTION: The hydrogen storage material is composed of amorphous carbon having a carbon film with the graphite structure on its surface. The preferable outer shape as its morphology is a coiled shape and the preferable aspect ratio is 3 to 10<7> . Further, it is preferable to improve the hydrogen storage ability by subjecting the produced hydrogen storage material to heating treatment or oxidation treatment or incorporating at least one of alkaline metals, alkaline earth metals, fluorine, iodine and sulfur into the storage material.
