NOVELTY - The method for preparing amorphous nickel-boron-graphene composite material involves (a) adding graphite powder to concentrated sulfuric acid in an ice bath, adding potassium permanganate, reacting, adding purified water and reacting, (b) adding hydrogen peroxide solution to the product (i), filtering and washing, (c) ultrasonically dispersing the product (ii), and (d) adding nickel chloride hexahydrate solution to graphene oxide dispersion, ultrasonically dispersing, heating, dripping sodium borohydride solution, cooling, filtering, washing and vacuum-drying to obtain the composite material. USE - Method is useful for preparing amorphous nickel-boron-graphene composite material, which is useful as a catalyst for hydrogenation of pinene. ADVANTAGE - The method enables simple preparation of the amorphous nickel-boron-graphene composite material with high catalytic activity. DETAILED DESCRIPTION - The method for preparing amorphous nickel-boron-graphene composite material involves (a) adding graphite powder to concentrated sulfuric acid in an ice bath, adding potassium permanganate, stirring for 1 hour, reacting at 15 degrees C for 2-4 hours, again reacting at 35 degrees C for 40-60 minutes, adding purified water and reacting at 80 degrees C for 30 minutes to obtain a product (i), (b) adding 30 %mass hydrogen peroxide solution to the product (i) to obtain a colloid, filtering, washing the filter residue with 5 %mass hydrochloric acid solution until no sulfate is found in the filtrate and again washing with distilled water until pH value of the filtrate is 7 to obtain a product (ii), (c) ultrasonically dispersing the product (ii) for 2 hours to obtain graphene oxide dispersion, and (d) adding nickel chloride hexahydrate solution to the graphene oxide dispersion, ultrasonically dispersing for 20 minutes, heating at 70-90 degrees C under a nitrogen atmosphere, dripping sodium borohydride solution under stirring condition, cooling to room temperature under nitrogen atmosphere, filtering, washing 3 times the filter residue with water and anhydrous ethanol, and vacuum-drying to obtain the composite material.
