27 Δεκ 2021 · Here, we have developed model Pt/TiO 2 catalysts based on the deposition of colloidal Pt nanoparticles and studied their atomic and electronic structures before and after a postdeposition treatment that induces catalytic activity using aberration-corrected scanning transmission electron microscopy, electron energy loss spectroscopy, and first ...
1 Ιουν 2023 · With the introduction of Pt particles onto the surface of TiO 2 supports, a junction is formed between the TiO 2 and Pt particles, which in turn enables the transport of light-generated “hot electrons” from Pt particles to the TiO 2 support.
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...
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 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...
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.
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.
