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.
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 · With the introduction of Pt particles onto the surface of TiO 2 supports, a junction is formed between the TiO 2 and Pt particles, which in turn enables the transport of light-generated “hot electrons” from Pt particles to the TiO 2 support.
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.
15 Ιουν 2024 · Through the identification of Pt precursor species and their excitation under LED-UV light, a photodeposition mechanism is proposed involving concurrent excitation of both the TiO 2 semiconductor...
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.
