Abstract:

Thermally-reduced graphene was obtained from reduction of graphene oxide (GO) via heat treatment under the hydrogen in the range of 300-1100°C. In order to find optimum tempreture, the synthesized graphenehas been investigated by X-ray diffraction (XRD), FTIR spectroscopy as well as Raman spectroscopy.The result indicated that the reduced graphene at 900°C (GR900) had the highest quality in comparison with the other temperatures. Additionally, GR900 exhibited a sharp (002) peak corresponding to an interlayer distance of 3.39° A, which is close to that of conventional graphene (3.4°A). However, the structure of GR900 was alsoinvestigated by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and the results supported the previous findings.
