▎ 摘　　要

NOVELTY - Preparation of loading platinum nanoparticle on graphene comprises taking restored graphene to ultrasonic disperse in glycol solution, adding glycol solution of 1-pyrene methylamine, and stirring for 20-120 minutes to self-assemble 1-pyrene methylamine on surface of the graphene; and adding 0.048 M chloroplatinic acid glycol solution (Nml), adjusting pH of glycol solution to 8-9 by 0.1 M sodium hydroxide, stirring, reacting for 2 hours in oil bath at 160 degrees C to obtain high-density loading platinum nanoparticle on graphene, cleaning and drying in freeze mode. USE - Method of preparation of loading platinum nanoparticle on graphene (claimed). DETAILED DESCRIPTION - Preparation of loading platinum nanoparticle on graphene comprises taking restored graphene to ultrasonic disperse in glycol solution, adding glycol solution of 1-pyrene methylamine, with ratio (mg:ml:ml) of graphene, glycol and glycol solution of 1-pyrene methylamine of 1:8-20:1-1.5, and concentration of glycol solution of 1-pyrene methylamine at 10-3 M, and stirring for 20-120 minutes to self-assemble 1-pyrene methylamine on surface of the graphene; and adding 0.048 M chloroplatinic acid glycol solution (Nml), with ratio (mg: ml) of graphene and Nml at 1:0.8-1.5, adjusting pH of glycol solution to 8-9 by 0.1 M sodium hydroxide, stirring, reacting for 2 hours in oil bath at 160 degrees C to obtain high-density loading platinum nanoparticle on graphene, cleaning and drying in freeze mode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the preparation of loading platinum nanoparticle on graphene.
