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 Ιουλ 2013 · Morphology index (MI) derived from FWHM of XRD data explains the interrelationship of particle size and specific surface area. It is observed that MI has direct relationship with particle size...
XRD patterns of nano-TiO2 in rutile and anatase phases exhibit broad peaks whereas both phases of micro-TiO2 demonstrate very sharp peaks. TEM images show that the grain size of TiO2 micropowders and TiO2 nanopowders are 0.3-0.7 μm and 10 nm, respectively.
23 Ιουλ 2019 · X-ray diffraction (XRD) patterns for samples of nanoparticles having different sizes and shapes can look different, and careful analysis of the XRD data can provide useful information and also help correlate microscopic observations with the bulk sample.
1 Ιουν 2023 · The results of the XPS analysis show that the Pt 4 f signal was detected for all the TiO 2 +Pt catalysts. The oxidation state of Pt was obtained by fitting the Pt 4 f spectra (Fig. S7).
1 Απρ 2015 · X-ray diffraction (XRD) is a powerful nondestructive technique for characterizing crystalline materials. It provides information on structures, phases, preferred crystal orientations...
The selected-area electron diffraction patterns of TiO2 nanopowders in rutile and anatase phases are consistent with XRD results. In this study, the commercial TiO2 nanopowder and micropowder of anatase phase and rutile phase have been characterized by x-ray diffraction (XRD) and transmission electron microscopy (TEM).
