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 ...

1 Ιουν 2023 · The TEM-selected area electron diffraction (SAED) patterns of the prepared TiO 2 +Pt catalysts (inset in Fig. 2, with ab-initio simulations for anatase, Pt, and their mixture) correspond to anatase TiO 2 and the minor presence of Pt in all the examined TiO 2 +Pt samples.
The SEM image (Figure 2D) reveals that these core–shell Pt@TiO2 structures appear like a large particle with scraggy surfaces and an average diameter of about 150 nm.
Based on energy dispersive X-ray spectroscopy (EDS) analysis, the amount of Pt nanoparticle loading was estimated to be 3.8 wt% and X-ray diffraction (XRD) measurement indicated that the ...
Pt/C-TiO2 photocatalysts with different amount of Pt (0.5–3.0 wt.%) were synthesized by the photodeposition method and were characterized in detail by X-ray powder diffraction (XRD), nitrogen...
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...
30 Σεπ 2023 · Out of various doping concentrations of Pt, 1.6% Pt-doped TiO 2 NTbs shows superior H 2 generation through photocatalytic water splitting reactions, which is attributed to the high electrical conductivity and stable electrical properties of it with a low impedance of 79 Ohms.
