Tóm tắt

This work dealt withusing ascosbic acid as reducing agentfor the reduction of graphene oxide (GO)to form reduced graphene oxide (RGO).Graphen oxide (GO) was synthesized via Hummers method. The GO and RGO materialswere characterized by X-ray diffraction (XRD), Fourier-transform infrared
spectroscopy (FT-IR), scanning electron microscopy (SEM), high resolution – transmission electron
microscopy (HR-TEM) and Brunauer – Emmett – Teller (BET). The results showed that the obtained
reduced graphene oxide (RGO) sample had a similar structure to the one of graphene and rather high surface area of 244.8 m2/g.
