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 ...
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 2016 · Charge separation and transfer at the interface between two materials play a significant role in various atomic-scale processes and energy conversion systems. In this review, we present the mechanism and outcome of charge transfer in TiO 2, which is extensively explored for photocatalytic applications in the field of environmental science.
5 Ιαν 2023 · The changes in electronic structure of elements Ti, O, and Pt were shown clearly by the XPS measurements, indicating the formation of Ti 3+-O v-Pt δ+ interfacial sites due to the charge transfer between Pt and mpTiO 2, which can be deemed as electronic MSI (EMSI).
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.
1 Ιουν 2023 · In addition, visible-light illumination of TiO 2 +Pt catalysts at temperatures below 200 °C beneficially increased the NO 2 conversion and lowered the ignition temperature of the deNO x process due to the Pt LSPR effect.
