15 Ιουν 2024 · To gain a deeper understanding of the enhancement of TiO 2-Pt photocatalytic activity through the photodeposition of Pt nanoparticles on the TiO 2 surface, we commenced our investigation by first recording the absorption and excitation spectra of the initial Pt precursor solutions.
15 Ιουν 2024 · This study presents a thorough spectroscopic analysis of TiO2-Pt systems under LED irradiation, with a focus on elucidating the photodeposition process of Pt nanoparticles onto TiO2...
XRD patterns of commercial titania show diffraction peaks attributed to the anatase (2θ ≈ 25 • ), rutile (2θ ≈ 28 • ), and mixed phases of TiO 2 , as reported by El-Desoky et al. [47 ...
12 Δεκ 2021 · After Pt loading, the XRD patterns of all the Pt/TiO 2 catalysts exhibited a characteristic Pt peak at 40° (Fig. 1), which corresponded to the (111) crystal face of Pt. However, the relative amounts of anatase and rutile phases for each type of support were similar before and after Pt loading.
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.
14 Φεβ 2020 · Herein, a novel TiO 2-based nano-sonosensitizer is reported to bilaterally enhance the quantum yield by simultaneous integration of precious metal Pt nanoparticles (NPs) and an oxygen-deficient layer.
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.
