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 ...
Pt@TiO2 core-shell nanostructures were prepared through a hydrothermal method. The dye-sensitization of these Pt@TiO2 core-shell structures allows for a high photocatalytic activity for...
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.
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).
1 Νοε 2018 · The synergistic effects of the high Schottky barrier at the Pt–TiO 2 -HA interface, which induces the stronger reduction ability of hot electrons, and intrinsic Pt catalytic activity are...
1 Ιουν 2023 · The TEM-selected area electron diffraction (SAED) patterns of the prepared TiO 2 +Pt catalysts (inset in Fig. 2, with ab-initio simulations for anatase, Pt, and their mixture) correspond to anatase TiO 2 and the minor presence of Pt in all the examined TiO 2 +Pt samples.
Analysis. The XRD patterns of different TiO 2 samples (bare and platinum loaded) are shown in Figure 2. The mean crystallite size (í µí°¿) of samples was calculated by Scherrer's equation (3)...
