15 Ιουν 2024 · This study presents a thorough spectroscopic analysis of TiO2-Pt systems under LED irradiation, with a focus on elucidating the photodeposition process of Pt nanoparticles onto TiO2 surfaces.
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°.
30 Σεπ 2023 · Out of various doping concentrations of Pt, 1.6% Pt-doped TiO 2 NTbs shows superior H 2 generation through photocatalytic water splitting reactions, which is attributed to the high electrical conductivity and stable electrical properties of it with a low impedance of 79 Ohms.
15 Απρ 2022 · In terms of Pt loading, it was demonstrated that the performance of 5.8 wt% Pt/TiO 2 was better than that of 0.7 wt% Pt/TiO 2. But, as Pt content was increased to 7.1 wt%, the photocatalytic performance exhibited a substantial downward trend under both acidic (pH 3) and alkaline (pH 9) conditions.
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 ...
23 Μαΐ 2020 · Herein we report a study of Pt-TiO 2 SMSI using Pt/rutile TiO 2 (110) model catalysts with different Pt particle sizes by means of X-ray photoelectron spectroscopy, ion scattering spectroscopy, and the adsorption of probe molecules.
