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 · 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.
30 Σεπ 2023 · With the increased Pt doping concentration on TiO 2, the material's electrons flow quickly from the TiO 2 valence band to the Pt conduction band, readily available at the surface of the material, and then more quickly towards the electrolyte.
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).
The XRD analysis of the prepared sample of TiO 2 nanoparticles was done using a Bruker make diffractometer, Cu-Kα X-rays of wavelength (λ)=1.5406 Å and data was taken for the 2 θ range of 10° to 70° with a step of 0.1972°.
Pt/TiO2 (PC500) photocatalysts with different amount of Pt (0.5–3.0 wt.%) deposited on commercial support (Al2O3 foam) were characterized in detail by X-ray powder diffraction, nitrogen ...
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...
