The XRD analysis of the prepared sample of TiO 2 nanoparticles was done using a Bruker make diffractometer, Cu-Kα X-rays of wavelength (λ)=1.5406 Å and data was taken for the 2 θ range of 10° to 70° with a step of 0.1972°.
1 Ιουν 2023 · In the XRD diffractograms of TNR and a-TNR+Pt samples, the intensities of anatase peaks are very strong, which provides evidence that the thermal treatment during the synthesis of TNR and a-TNR+Pt solids caused the crystallization of the amorphous TiO 2 shell in the a-TNR support into anatase phase. The average anatase crystallite size was ...
15 Ιουν 2024 · This study presents a thorough spectroscopic analysis of TiO 2 -Pt systems under LED irradiation, with a focus on elucidating the photodeposition process of Pt nanoparticles onto TiO 2...
Titanium oxide (TiO2) nanoparticles were fabricated using the sol-gel technique. By controlling the calcination temperature, the different structures of TiO2 (anatase and rutile) have been...
30 Σεπ 2023 · XRD studies. The XRD patterns of TiO 2 NTbs and Pt-doped TiO 2 NTbs are shown in Fig. 3. Peaks at 25°, 38°, 48°, 54°, 55°, 63°, and 75° indicated the presence of planes of the anatase phase of TiO 2 such as (101), (004), (200), (105), (211), (204), and (215), respectively.

6 Απρ 2010 · In real-life samples, TiO 2 is most likely to be a mixture of those phases rather than pure anatase and rutile, and therefore quantitative analysis is extremely important. It is basically possible to determine the average ratio by X-ray diffraction (XRD) using differences in the crystal structure, but it is not easy to do so when attempting ...
