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 ...
Electron transfer not only between the substrate and the photocatalyst but also inter‐ and intramolecularly, is an important consideration for reaction design. Radical cations were generated by...
1 Ιουν 2023 · S9 presents a scheme of the band gap diagram of the TiO 2 support/Pt particles system and schematically shows the formation of SBH and the transfer of visible-light-generated “hot electrons” from Pt particles to the TiO 2 support.
The catalysts characterized by SEM, EDX, DRS, and XRD techniques showed successful deposition of Pd and Pt atoms on TiO2 surface that enabled light absorption in the visible (Vis) range,...
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).
15 Απρ 2022 · The authors depicted that deposited platinum has the mediating role in trapping and transfer of photo-generated electrons from the TiO 2 to an acceptor, thus facilitating charge separation and enhancing the rate of hydrogen evolution over Pt/TiO 2 photocatalysts.
The synthesized Er³⁺/TiO2 and Ni²⁺/TiO2 catalysts were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX), metal...
