NOVELTY - Preparing aminated graphene comprises orderly adding sodium hydroxide and chloroacetic acid in enriched graphene aqueous solution, stirring and reacting, centrifugally washing, dissolving the carboxylated graphene, centrifuging, washing freezing and drying, dissolving the graphene powder in N-methyl pyrrolidone, adding phosphorus oxychloride, reacting, distilling, dehydrating, mixing cyanide graphene and catalyst, reacting and carrying out catalytic hydrogenation. USE - The method is useful for synthesizing high doping amount of aminated graphene. ADVANTAGE - The method: is simple. DETAILED DESCRIPTION - Preparing aminated graphene comprises (a) orderly adding sodium hydroxide and chloroacetic acid in a molar ratio of 1:1 in 0.5-2 mol/l enriched graphene aqueous solution, stirring and reacting for 3-12 hours at 15-50 degrees C and centrifugally washing until the pH value of the centrifugal liquid is 7, to obtain carboxylated graphene, (b) dissolving the carboxylated graphene to fully disperse in the solution, to obtain 1 mg/ml carboxylated graphene solution, adjusting the pH value with ammonia water to 10-12, stirring for 6-12 hours, centrifuging, washing until the pH value of the washing liquid is 7, to obtain graphene solution, freezing and drying, to obtain the acylamino graphene powder, (c) dissolving the graphene powder in N-methyl pyrrolidone, adding phosphorus oxychloride, reacting at 40-100 degrees C, stirring for 3-15 hours, vacuum distilling to remove phosphorus oxychloride and amido graphene and dehydrating, to obtain cyano-graphite alkene, (d) mixing cyanide graphene and catalyst in a ratio of 1:1-1:10, mixing based on 100-300 ml/minute hydrogen gas, reacting at 500-1000 degrees C for 3-10 hours and carrying out catalytic hydrogenation.
