For instance, XRD results clearly demonstrate that some new diffraction peaks of Nb3O7F appear after 8 h of reaction. In addition, this has also been confirmed by SEM observation. With increasing the reaction time to 8 h, some sheets are formed besides those nanorods. The thickness of ...
X-ray diffraction (XRD) patterns of pure In2O3 nanofibers (Fig. 1f) indicate the monoclinic phase (PDF#71-2195), while characteristic peaks corresponding to Nb2O5 (PDF#30-0873) emerge in the INx composites at 20 wt.% Nb2O5 content, signifying the successful synthesis of In2O3/Nb2O...
The XRD pattern of KNbO sample prepared by solvothermal treatment is shown in Fig. 1a. All of the XRD peaks can be assigned to the orthorhombic K4Nb6O17·4.5H2O phase (JCPDS No. 21-1296, P22121, a = 7.82 Å, b = 41.09 Å, c = 6.42 Å, α = β = γ = 90°). The dif...
XRD pattern of the Nb2O5 support exhibits peaks characteristic of the pseudohexagonal TT-Nb2O5 phase (Ko and Weissman, 1990). Notably, a high-intensity signal is observed at 22.8°, which is associated with (001) reflection of TT-Nb2O5. In addition, a low-intensity and broad signal ...
No diffraction peaks of Ru were observed in the XRD patterns, while all the peaks of Pt were in accordance with the face centered cubic crystal structure. The binding energy of Pt was not affected by NbO·HO. Compared with 20%Pt10%Ru/C, in 10%NbO·HO-20%Pt10%Ru/C samples, the ...
Figure2shows the XRD patterns of anodized aluminium monoliths and Nb2O5/Al2O3/Al catalyst. The crystallographic planes were identified according to JCPDS database. The alumina generated during the anodization process exhibited an amorphous structure, which is in good agreement with the results previo...
Electrochromic PropertyNb2O5:MoO3 (95:5 and 85:15) thin films were deposited onto glass and fluorine doped tin oxide coated glass substrates at 100 and 300 °C by RF magnetron sputtering technique. The physical and electrochromic properties of the films were studied. XRD result reveals that ...
Powdered X-ray diffraction (XRD) pattern of the as-obtained samples is shown in Fig. 1d. All diffraction peaks are indexed to the hexagonal Nb2O5 (PDF#07-0061) phase and monoclinic Nb2O5 (PDF#19-0862) phase and no impurities are observed. Transmission electron microscopy (TEM) and ...
Rh doping led to no peak shift in the XRD pattern of Nb2O5(FigureS2). The inset of Fig.3shows a predicted energy diagram of Nb2O5:Rh-NW, which is constructed based on earlier studies36,37. The energy-gap values for Nb2O5:Rh-NW are as follows: the energy gaps between the valen...
It is observed in XRD some characteristic peaks (0 0 1), (1 8 0), (1 8 1), (0 0 2), (3 8 0) and (2 1 2), which correspond to the reflection planes characteristic of Nb2O5 orthorhombic phase (Raba et al., 2016). The peaks were cataloged using Match® Software in comp...
