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.
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...
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.
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.
24 Μαΐ 2016 · The presence of Pt deposits on TiO 2 is believed to retard the rapid charge-pair recombination by serving as an electron sink and facilitating interfacial electron transfer to dioxygen or...
30 Απρ 2024 · The removal of surface hydroxyl groups on PtO x promoted strong electronic coupling of the Pt 5d orbital in PtO x and C 2p orbital in toluene, facilitating the electron transfers from toluene to PtO x and subsequently the adsorption/activation of toluene.
