▎ 摘　　要

NOVELTY - Preparing graphene-platinum nano-composite material by using argon plasma, comprises: (a) taking graphene oxide (48-52 mg) in a beaker, adding chloroplatinic acid (1.8-2.2 ml) with a concentration of 0.8-1.2 mol/l, mixing, placing the mixture in an oven, drying at 58-62 degrees C to obtain the dried powder; (b) placing the dried powder in a sealed container, generating argon plasma flow, contacting argon plasma stream directly on the surface of the dried powder for 28-32 minutes, discharging, de-ionizing and washing the reaction product with suitable organic solvent, filtering, and drying. USE - The method is useful for preparing graphene-platinum nano-composite material by using argon plasma. ADVANTAGE - The method is simple; shortens production time; and produces uniformly distributed platinum-graphene nano-composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the device for preparing graphene-platinum nano-composite material by using argon plasma (Drawing includes non-English language text).
