The reduction of graphene oxide (GO) was processed in an atmospheric pressure plasma discharge with several gas mixtures consisting of the combination of H-2, Ar, N-2 and CH4. Oxygen-containing functional groups on the surface of the graphene oxide were effectively and rapidly removed in the ambient atmosphere of H-2 containing plasma discharge without artificial heating. An increase of the H-2 concentration in the feed gas mixture, applied AC voltage, and process time generally enhanced the reducing efficiency of the graphene oxide. The atomic carbon concentration of 68.81% was changed to 89.34% in the H-2/N-2 plasma after 30 min. The result shows that the plasma treatment is a practical and effective method for the reduction of graphene oxide.
