1c). Previously, it has been reported that by the analysis of shape, width and position of 2D peak, the layer number in graphene may be distinguished32. In our rGO sample, the position and shape of 2D peak suggest the formation of few layer (3 to 4 layer) graphene after the thermal...

The successful interface between TiO2 and rGO was confirmed by the broadening characteristic of the XRD peak for anatase TiO2, increasing D and G band intensity ratios (ID/IG) of Raman spectra from 1.05 to 1.9, and decreasing intensity of UV–Vis transmittance spectra as the rGO concentration ...
Compared with α-Fe2O3, the peak intensity of NG-Fe2O3, GO-Fe2O3 decreased dramatically. No obvious peaks related to graphene oxide were observed from the XRD Conclusion In conclusion, a pyrrolic-N doped graphene oxide/Fe2O3 mesocrystal nanocomposite has been prepared by a simple ...
The XRD study (Figure 2) clearly indicates by comparison of the (002) diffraction peak position that graphite was fully oxidized and the GOs were reduced after the solvothermal reaction. Figure 2. Powder X-ray diffraction of (a) graphite, (b) GOs, and (c) m-RGOs. The weak intensity ...

The aim of this work was to prepare and characterize nanocomposites containing graphene from intercalated graphite. The graphene was produced by rapid thermal expansion using expandable graphite oxide or obtained commercially. The polymer used was poly(s
Hydrazine hydrate as reducing reagent was added to prepare reduced graphene oxide (RGO). GO and RGO were characterized by XRD, SEM and Raman. According to the peak position and intensity of the D, G and G′ band in Raman spectra, the influence of KMnO4, H2O2 and hydrazine hydrate on the...
Ag nanoparticle decorated reduced graphene oxide (rGO-Ag) have been synthesized successfully by simultaneously reducing graphene oxide and AgNO_3 with hydrazine hydrate as reducing agent. The synthesized rGO-Ag has been characterized by X-ray diffraction (XRD), field emission scanning electron ...
Based on the treatment and characterization conducted, all samples were likely to contain reduced graphene oxide (RGO) phase.The XRD data have supported the existence of RGO with the diffraction peak position (2q) at 25o and 45o. Evidence is also given by the result of Raman Spectroscopy ...
