NOVELTY - Alkane dehydrogenation catalyst comprises graphene having at least one structure selected from an atom vacancy structure, a 1-hydrogenated atom vacancy structure, a 2-hydrogenated atom vacancy structure, a 3-hydrogenated atom vacancy structure, and a nitrogen-substituted atom vacancy structure. USE - The catalyst is used for producing hydrogen production apparatus for producing hydrogen as renewable energy and ammonia production apparatus for producing ammonia (claimed) from an alkane without emission of carbon dioxide for fuel cell vehicle. ADVANTAGE - The catalyst generates electricity or burn it for use as heat energy, transports and stores hydrogen energy, achieves energy carrier, can be safely stored in a large amount without emitting carbon dioxide and has excellent hydrogen adsorption power. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for producing the alkane dehydrogenation catalyst involving colliding high-energy particles with the raw material graphene; (2) a method for producing hydrogen involving extracting hydrogen from an alkane using the alkane dehydrogenation catalyst; and (3) a method for producing ammonia involving using hydrogen obtained in above-mentioned method to reduce nitrogen oxides to obtain ammonia.
