23 Ιουλ 2024 · Here, the dynamic nature of Pt/CeO2 during the water-gas-shift reaction is studied using multiple in situ characterization tools to establish structure-performance relationships.
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.
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 Δεκ 2008 · Three-dimensionally ordered macro-porous (3DOM) Pt/TiO 2 catalysts were prepared by template and impregnation methods, and the resultant samples were characterized by using TG-DTA, XRD, SEM, TEM, and TPR techniques. The catalytic performance for water-gas shift (WGS) reaction was tested, and the influences of some conditions, such as reduction ...
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...
4 Ιουν 2021 · The application of single-atom catalysts (SACs) to high-temp. hydrogenation requires materials that thermodynamically favor metal atom isolation over cluster formation. We demonstrate that Pd can be predominantly dispersed as isolated atoms onto TiO2 during the reverse water-gas shift (rWGS) reaction at 400°C.
