In X-ray diffraction (XRD) patterns (Fig.2a), GO shows the characteristic (001) peak associated to the carbon crystalline phase and the (100) peak related to the lateral dimension of basal planes at 10.80° and 42.57°, respectively45,46. St has instead the typical features of the B-typ...
The powder X-ray diffraction (XRD) pattern of the prepared G-O was compared with those of the RG-Os depicted in Figure 1c. The peak position for graphite powder was 2θ = 26.7° (d-spacing ~3.34 Å). A typical broad peak near 10.27° (d-spacing ~8.60 Å) was ...
The abscissa of RG represents the offset distance between asphalt model centroid and selected molecule centroid, while the peak point position of Rg closer to the zero point (the centroid of model) has higher density in molecular system, and the smaller peak width means the molecular branch ...
XRD is used to characterize the graphene quality by probing the amount and orientation of graphitic carbon layers and the curvature of individual sheets [48]. As shown in Fig. 2b, GO shows a sharp peak at ~ 11.7°, while PI exhibits a broad peak at ~ 21.1° due to its ...
the average crystallite size was estimated by the Scherrer equation (Cheng et al.2017). The 2θ position of the diffraction peaks of the XRD patterns was determined by X-ray diffraction. The peaks were identified with the help of database Joint Committee on Powder Diffraction Standards (JCPDS)...
XRD tests were employed to investigate the crystal structure of the pure GL-C3N4, MoO2 and the as-prepared MoO2/GL-C3N4 composites (Fig. S1). This strongest XRD peak at 2θ = 27.8° corresponded to the characteristic peak (0 0 2) of GL-C3N4 [20]. XRD pattern of MoO2 nan...

The 2D peak of the graphene film was near 2700 cm−1. The 2D peak is derived from the dual resonant electron- photon scattering process, and its peak position and intensity were used to identify the number of graphene layers. The G peak near 1580 cm−1 was the characteristic peak of...
(δ) peak corresponding to the polystyrene phase of SBS using CT >700 m2/g graphene at 1% (w/w). The SBS graphene composites were insulators at 1% (w/w). The styrene groups in SBS isolate the graphenes preventing a percolation network that would enhance electrical permittivity (a feature ...
XRD patterns of all synthesized graphene products as shown in Figure 2 demonstrated a peak at 2θ = 26.5° which is characteristic of carbonaceous materials. Although graphene samples and CGr have the same peak position at 2θ = 26.5°, the peak intensities of the graphene products synthesized ...
