XRD-TiO2-Rutile
Generally, the decreased intensity of TiO2 XRD peaks indicates the nanocomposite (TiO2/rGO at 7 and 10 wt%) are less crystalline or has an amorphous-like structure, possibly due to the low calcination temperature during the deposition process [57], [58]. However, this is uncorroborated by ...

The absence of rutile TiO2 in XRD result may due to its low amount. After H2O2 oxidation, unstable TiO disappeard and anatase TiO2 formed in the H2O2-TiO2 structure (Figure S1A and C). However, the intensity of XRD peaks of anatase TiO2 was relatively low. The transmission electron ...
area thin films but provides excellent control of the growth condition to obtain a high-quality thin film. High-resolution X-ray diffraction (HR-XRD) and high-resolution transmission electron microscopy (HR-TEM) measurements show high crystalline qualities of anatase and rutile epitaxial thin films....
(A4), the peaks become more dominant and narrower due to microcrystalline sintering (Fig.6). However, the A4 TiN reflections were shifted to low angle in comparison to the low nitrogen-doped materials, indicating an expanded unit cell. Of additional note, the presence of rutile was not ...
The synthesized films are investigated by XRD, Raman spectroscopy and XPS. The diffraction peaks of anatase phase fade while the peaks of rutile phase appear in the X-ray profiles with increasing of the treatment temperature and the content of SnO2 in the sprayed films. It is found that SiO2...
2f) [34]. Powder XRD pattern of the IrO2@TiO2 is shown in Fig. 3a, revealing sharp typical peaks of rutile IrO2 [35], confirming the high crystallinity of the IrO2 shells. The result also revealed the majority of rutile TiO2 besides anatase TiO2 for the core. The mean crystal size ...
Figure 2a shows the XRD patterns of the synthesized samples; all peaks of the samples were indexed to TiO2 (anatase, JCPDS: 99-0008) and rGO. Because of the high crystallinity of rGO/TiO2-7Ar, the low-intensity, broad rGO peak at 2θ = 24.5° is obscured by a TiO2 peak. By co...
1h). The O1s spectrum revealed two peaks at 532.4 eV and 535.1 eV, which indicates the presence of C=O and C–O (Fig. 1i). Moreover, the obtained FT-IR and XPS data reveal the surface wettability of the prepared DP-CDs. The presence of hydroxyl and carboxyl (hydrophilic) groups ...
