Reduced graphene oxide (RGO) film was prepared by vacuum suction of graphene oxide (GO) solution followed by atmospheric argon plasma treatment. In particular, atmospheric plasma treatment on GO film exhibited fast reduction in less than 30 seconds, with comparable degree of reduction with conventional chemical reduction method. Moreover, additional XPS, IR, XRD, TGA analyses indicated that as-prepared RGO film possessed negligible hetero-atom content, while showing low O/C ratio. Electrochemical analyses were also conducted to evaluate possibility of as-prepared RGO film for energy storage application. This green methodology can offer a novel pathway for synthesizing RGO without chemical agent in short time. |
