  • Carbon-based hydrogen storage material having autocatalytic capability, production method thereof, and hydrogen adsorbing—storing method, hydrogen releasing method, and hydrogen adsorption—storage device using thereof
    Patent number: 11072524
    Abstract: The objective of the present invention is to provide a carbon-based hydrogen storage material having an autocatalytic capability and an atomic vacancy, wherein the hydrogen storage is a hydrocarbon compound which produces a non-endothermic release or an exothermic release of hydrogen adsorbed in the compound. In addition, the present invention provides a method of manufacturing the material comprising: preparing a hydrocarbon compound as the raw material of the carbon-based hydrogen storage material; setting the raw material in a container having a predetermined gas partial pressure; producing the hydrocarbon compound by ion beam irradiation of the raw material; performing annealing treatment under the predetermined conditions; and exposing the product to the hydrogen under the predetermined conditions, wherein the product is a hydrogen storage hydrocarbon compound producing a non-endothermic or an exothermic release of hydrogen adsorbed thereto with autocatalysis activity.

  • CARBON-BASED HYDROGEN STORAGE MATERIAL HAVING AUTOCATALYTIC CAPABILITY, PRODUCTION METHOD THEREOF, AND HYDROGEN ADSORBING - STORING METHOD, HYDROGEN RELEASING METHOD, AND HYDROGEN ADSORPTION - STORAGE DEVICE USING THEREOF
    Publication number: 20190233282
    Abstract: 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.
