1 Ιουλ 2022 · X-ray diffraction (XRD) patterns for the different TiO 2 polymorphs before and after Pt SA immersion deposition from a 0.005 m m precursor solution are shown in Figure 3c. According to the XRD patterns, all samples are highly crystalline and contain either pure anatase (PDF#21–1272), pure rutile (PDF#21–1276), or a mixture of both anatase ...

Fourier transform infrared spectroscopy (FTIR) analysis identified a peak around 545 cm⁻¹ in the TiO2@AC-2 sample, indicative of O-Ti-O stretching vibrations. This peak shifted to 602 cm⁻¹...
Download scientific diagram | XRD patterns for rutile, anatase, and mixed TiO2 phases. The JCPDS #75-1537 for TiO2 is shown as a reference.
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.
XRD pattern of TiO 2 nanoparticles The X-ray diffraction pattern of the synthesized Titania nanoparticles is shown in Fig.1 and the peak details are in Table.
To enhance its photocatalytic activity, TiO2 was doped with Pt. The synthesised photocatalyst was characterised by techniques such as particle size analysis (PSA), XRD, FE-SEM, TEM, and EDX.
Summary: Rietveld Basics. Calculate XRD pattern from model structure. Minimize differences between calculated and measured pattern. Accurate mathematical description of peak profile required: Classical Rietveld approach: Fit a peak shape function (PV or similar) to reference pattern.
