摘要

The objective of the present invention is to provide a carbon-based hydrogen storage material having an autocatalytic capability, and a production method therefor. The present invention provides a carbon-based hydrogen storage material having an atomic defect, which is a hydrogen adsorbing-storing hydrocarbon compound having an autocatalysis reaction, wherefrom hydrogen that has been adsorbed and stored within the compound is either released while no heat is absorbed, or released while heat is generated. In addition, provided is a production method for the carbon-based hydrogen storage material having the autocatalytic capability, comprising: preparing a hydrocarbon compound serving as a production starting material for the carbon-based hydrogen storage material; setting the production starting material inside a container under a predetermined partial gas pressure; irradiating the production starting material with an ion beam and then performing annealing under predetermined conditions, thereby forming the hydrocarbon compound having the atom defect; and processing with activated hydrogen the hydrocarbon compound having the atom defect. Also provided is a production method for a hydrogen adsorption-storage device using the carbon-based hydrogen storage material.
