Özet:

 

In this study, the effects of starting material types on   graphene oxide (GO) are reported with the aim of developing graphene (GR)   synthesis. The GOs were prepared from natural graphite (NG) powder and   graphite nanoplate (GNp) based on the Hummers method. Two kinds of GR were   successfully synthesized using GOs, which were prepared from NG and GNp in   the presence of hydrazine and ammonia for 24 h at a 100 ∘∘^{\circ}C reaction   temperature. The synthesized GOs and GRs were characterized by X-ray   diffraction (XRD) techniques, Fourier transform infrared, high-contrast   transmission electron microscopy (HCTEM), dispersive Raman spectroscopic   analyses, and elemental analyses. HCTEM analyses of GOs and GRs exhibited   largely folded, convoluted, and entwined GO and GR structures. The XRD and   Raman analyses showed that the number of layers of GO1, GO2, GR1, and GR2   were 9.27, 13.53, 4.11, and 5.26, respectively. On the other hand, GR1,   prepared from NG powder, showed much higher quality (peak intensities   (IDD_{D}/IG)G)_{G}) = 1.53, C/O = 3.64) than GR2, which was prepared from GNp   (IDD_{D}/IGG_{G\, }= 1.64, C/O = 3.17). Thus, this study provides a way to   produce higher quality GOs and GRs.
