1 Νοε 2018 · This methodology affords us to successful access to the novel plasmonic Pt/TiO2-HA (large Pt nanoparticles (NPs) supported on TiO2 hierarchical nano-architecture (TiO2-HA)) photocatalysts...
15 Ιουν 2024 · This study presents a thorough spectroscopic analysis of TiO 2 -Pt systems under LED irradiation, with a focus on elucidating the photodeposition process of Pt nanoparticles onto TiO 2...
30 Σεπ 2023 · Pt forms a Schottky barrier at the interface of TiO 2, and this barrier improves the efficiency of photocatalytic reactions [6] compared to other dopants. Pt increases electron capture and therefore reduces the rate of electron–hole pair recombination.
15 Απρ 2022 · Photocatalysis. Energy and environmental applications. 1. Introduction. Over the past decades, many start-of-the-art and momentous studies have been carried out to meet energy demand and overcome the environmental degradation as an imminent problem.
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, PtO 2, and TiO 2 after thermal oxidation. Field emission scanning electron microscopy reveals a uniform Pt coating on Ti6Al4V with a thickness of 2–3 µm.
The experimental XRD pattern agrees with the JCPDS card no. 21-1272 (anatase TiO2) and the XRD pattern of TiO2 nanoparticles other literature [8]. The 2θ at peak 25.4° confirms the TiO2 anatase structure [9]. Strong diffraction peaks at 25° and 48° indicating TiO2 in the anatase phase [10].
