In TRGO, the peak position (26.3 Å) was nearly same as that of CRGO, but FWHM was found to be reduced which indicates the higher degree of ordering as compared to CRGO (Supplementary Fig. S3). Raman spectroscopy was utilized to characterize graphene structure, structural changes during...
Upon comparison with BG, the C (002) peak position of BG-AgNW gets broader and shifts to 24.98°, suggesting the successful insertion of AgNWs. This insertion prevents the restacking of BG. The peak broadening and the increased d-spacing of C (002) peak can also be attributed to the ...
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 ...
XRD analysis XRD is an effective technique to investigate the interlayer changes and the crystalline nature of the synthesized material. XRD patterns of GO and S-rGO are shown in Figure2. Pristine graphite exhibits a basal reflection (002) peak at 2θ= 26.6° corresponding to adspacing of 0.33...
The XRD patterns of GO and Mn3O4/x% GO NC’s for every samples are shown in Fig. 1. Figure 1a shows the spectra of GO peaks. A strong peak at 11.56° corresponds to the reflection of the (001) plane of graphene oxide. Another small broad peak at 41.84° corresponds to the reflec...
Regarding to the work of Ruland and Smarsly [34], all these parameters contribute to the profile shape of the (00l) reflections, and a3 min has an especially significant influence on the peak position. Therefore, the refined values for a3 min and σ3 in this study might be different ...
The peak position of GO in the XRD patterns is another indicator for determining the degree of oxidation. The oxygen functional groups are located at the edges and surfaces of the GO sheets, which make the GO highly hydrophilic. Upon oxidation, as the solution pH was increased by washing and...
(100) peak signifies the orientation and arrangement of carbon atoms within the graphene plane and can be indicative of the material’s degree of crystallinity. Notably, the XRD pattern inFigure 5a unveils a pronounced alignment with the (002) and (100) crystallographic planes, indicative of a ...
If the CT graphene is single layer (as determined by the 2D peak), then the GT graphenes also contain single layers (as indicated by the G peak). Figure 5 Raman spectra comparing the G peak position of graphene produced using four different methods. 3.2.4 D/G ratio The D/G ratio can...
Background subtraction was performed using the Shirley process for peak fittings. After N2 plasma treatment of Gr to form N-doped Gr, the primary C 1s peak, centered at 284.48 eV, shows a clear shift to a higher binding energy relative to the position of the pure sp2 hybridized C=C...
