  1. Based on energy dispersive X-ray spectroscopy (EDS) analysis, the amount of Pt nanoparticle loading was estimated to be 3.8 wt% and X-ray diffraction (XRD) measurement indicated that the...

  2. This synthesized heterogeneous photocatalyst (Pd/TiO2) was characterized through field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM),...

  3. 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.

  4. 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 ...

  5. 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,...

  6. 5 Ιαν 2023 · Electronic interactions between metal nanoparticles and oxide supports control the functionality of nanomaterials, for example, the stability, the activity and the selectivity of catalysts. Such interactions involve electron transfer across the metal/support interface.

  7. 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.
