| Abstract: | Graphene has been synthesized by four different methods namely, pyrolysis of camphor under reducing conditions (CG), exfoliation of graphitic oxide (EG), conversion of nanodiamond (DG) and arc evaporation of graphite rod in hydrogen atmosphere (AG). The samples were examined by X-ray diffraction (XRD), transmission electron microscopy (TEM), atomic force microscopy, Raman spectroscopy and thermogravimetric analysis. Raman spectroscopy shows EG and DG to exhibit smaller in-plane crystallite size around 4-5 nm, while CG exhibits higher in-plane crystallite size of around 10 nm. From XRD and AFM studies, HG turns out be the best means of preparing graphene with a small number of layers. |
