FIELD: hydrogen power engineering.
SUBSTANCE: invention relates to hydrogen power engineering, specifically to the technology of producing efficient hydrogenation catalysts, which can be used in making hydrogen-accumulating materials and devices based thereon. Method of producing a nickel-carbon-graphene hydrogenation catalyst involves dispersing an aqueous solution of nickel acetate Ni(CH3COO)2 in an aqueous suspension of graphite oxide, drying the aqueous dispersion at atmospheric pressure, followed by annealing the mixture in an inert gas stream and reducing graphite oxide and nickel (II) with a gas mixture Ar:H2:ethylene with simultaneous synthesis of carbon nanofibres in a stream of this mixture Ar:H2:C2H4 at temperature of 700 °C.
EFFECT: reduced duration of production and increased output of nickel-carbon-graphene catalyst.
