The Rietveld refinement of XRD pattern has indicated that the gamma-Fe2O3 shows a cubic cell structure. The superstructure reflection related to the long-range ordering of cation lattice vacancies was not detected in the diffraction pattern. The extra peaks corresponding to the Lepidocrocite phase ...
The structural properties of the Fe2O3NPs were assessed using XRD, as demonstrated in Fig.1a, which shows the hematite’s X-ray diffraction pattern after it has been annealed for three hours at 550 °C. There are multiple diffraction peaks in the sample’s XRD pattern (012), (104), (...
The XRD pattern of the CsPbBr3 gamma irradiation with doses ranging from 0 to 100 kGy, as shown in Fig. 1, had peaks of (1 0 0), (1 1 0), (1 1 1), (2 0 0), (2 1 0), (2 1 1), and (2 2 0) positioned at 14.96, 21.40, 25.22, 30.32, 34.04, 37.59, and 43.77,...

Efficient adsorbent gamma-Fe2O3/SiO2 nanocomposites were synthesized using sol-gel method. The developed adsorbent was well characterized using various analytical techniques such as XRD, TEM, SEM, BE and DRS techniques. The obtained XRD pattern that revealed a strong Si (111) peak at 28.1 ...
Furthermore, the FT-IR spectrum and XRD pattern of the recovered catalyst showed no critical change to those of the fresh one.Mahdian, AbolfazlArdakani, Mehdi HatefiHeydari-Bafrooei, EsmaeilSaeednia, SamiraVali E Asr Univ Rafsanjan Dept Chem Fac Sci Rafsanjan 7718897111 IranApplied Organometallic...
The wide-angle XRD pattern of non-stacked γ-Fe2O3/C@TiO2 is shown in Figure 2a. The characteristic peaks of the catalyst were indexed to anatase TiO2 (JCPDS-ICDD21-1272) [21,22,23]. Other phases such as γ-Fe2O3 were not observed because the thick TiO2 shell passivated the X-ray...
