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.
30 Ιουλ 2024 · The coated surfaces are characterized by X-ray diffraction (XRD), showing the characteristic peaks of Pt deposited and the presence of Pt, PtO2, and TiO2 after thermal oxidation. Field emission scanning electron microscopy reveals a uniform Pt coating on Ti6Al4V with a thickness of 2–3 µm.
22 Μαΐ 2024 · Understanding the behaviour of photogenerated carriers and the charge transfer pathways at the TiO 2 /water interface is, thus, of great relevance and can help improve the performance of TiO...
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...
18 Φεβ 2019 · Herein, novel synchronous illumination X-ray photoelectron spectroscopy combined with an angle-resolved technique (AR-SI-XPS) was employed for the first time to identify the interatomic electron transfer and interface bond changes on Pt/TiO2 photocatalysts, which could promote overall water splitting while r.
The coated surfaces are characterized by X-ray diffraction (XRD), showing the characteristic peaks of Pt deposited and the presence of Pt, PtO2, and TiO2 after thermal oxidation. Field emission scanning electron microscopy reveals a uniform Pt coating on Ti6Al4V with a thickness of 2–3 μm.
15 Απρ 2022 · For this reason, the introduction of platinum (Pt), known as a noble metal, into TiO 2 structure has been considered as an effective strategy. This strategy presents a better separation efficiency of electron-hole pairs resulting in a higher photocatalytic activity of the catalyst.
