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 · The results of this study show that the prepared TiO 2 +Pt plasmonic catalysts can be used as photo, thermal and photothermal catalysts in both gas-solid and gas-liquid-solid environmental applications, and that the catalytic performance of the examined solids depends on their morphological, optical and electronic properties, as well as on the ...
1 Οκτ 2013 · Periodic density functional theory calculations and microkinetic modeling are used to illustrate the specific role of the three-phase boundary (TPB) in determining the activity and selectivity of TiO 2-supported Pt catalysts for the water–gas shift (WGS) reaction.
1 Νοε 2018 · Particularly, the Pt/TiO2-HA shows an excellent photocatalytic activity for overall water splitting rather than only for hydrogen evolution (HE), which is superior to those of the...
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 Ιουν 2024 · This study presents a thorough spectroscopic analysis of TiO 2 -Pt systems under LED irradiation, with a focus on elucidating the photodeposition process of Pt nanoparticles onto TiO 2...
9 Αυγ 2017 · Pd functionalized TiO 2 nanoparticles were synthesized by a facile hydrothermal method. The structure, morphology, surface chemical states and surface area were characterized by X-ray diffraction...
