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.
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.
5 Ιαν 2023 · Pt nanoclusters confined in ordered mesoporous TiO2 facilitate the generation of interfacial active sites (Ti3+-Ov-Ptδ+) during the reaction, enhancing the cyclic catalytic activity.
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...
1 Δεκ 2023 · Prepared TiO 2 nanorods were characterized by XRD and evidenced nanorods morphology through high resolution scanning electron microscope (HR-SEM). We have performed a detailed study on the current-voltage (I-V) characteristics of the prepared heterojunction device (Pt/TiO 2 /FTO).
17 Νοε 2021 · The present manuscript summarizes the main findings of previous literature reports and, also on the basis of some novel experimental evidences, tentatively proposes that the energy transfer in TiO2 photocatalysis could possess a Förster-like nature.
