Method for preparing grapheme platinum nanocomposite material by using argon plasma

Abstract

The invention discloses a method for preparing grapheme platinum nanocomposite material by using argon plasma. The method comprises the steps of: putting graphene oxide into a beaker, then adding chloroplatinic acid, drying the obtained mixture, then putting the mixture into a sealed container, wherein the container is connected with a graphite electrode, the electrode is connected with alternating current power supply, and the power supply can generate an inductive coupling plasma source; introducing argon into the container, removing air, then opening a vacuum pump to vacuumize until the vacuum degree is about 3Pa; opening the alternating current power supply to generate the argon plasma, enabling the plasma flow directly to act on the surface of the dried powder for 28-32 minutes, fully washing, filtering and drying the reaction product by deionized water and proper organic solvent to prepare the grapheme platinum nanocomposite material. According to the method, not only can uniformly distributed grapheme platinum nanocomposite material be prepared effectively, but also the preparation time is shortened greatly, and the process is simplified.
