CO Oxidation Mechanism on CeO2-Supported Au Nanoparticles
TL;DR: The results provide a design strategy for CO oxidation on supported Au catalysts by lowering the vacancy formation energy of the supporting oxide, and using an easily reducible oxide to increase the concentration of reduced metal ions, which act as anchoring sites for O(2) molecules.
Journal ArticleDOI
Bifunctional Mechanism of CO2 Methanation on Pd-MgO/SiO2 Catalyst: Independent Roles of MgO and Pd on CO2 Methanation
TL;DR: In this paper, the authors scrutinized the reaction mechanism of CO2 methanation catalyzed by a Pd-MgO/SiO2 catalyst and found that MgO initiates the reaction by binding a CO2 molecule, forming a magnesium carbonate species on the surface.
Journal ArticleDOI
Catalytic CO Oxidation over Au Nanoparticles Supported on CeO2 Nanocrystals: Effect of the Au–CeO2 Interface
TL;DR: In this paper, the effect of a surface structure of supporting oxides and the corresponding CO oxidation activity of supported Au NPs was investigated. But the results were limited to the case of shape-controlled Au/CeO2 cubes.
Journal ArticleDOI
CO Oxidation at the Interface of Au Nanoclusters and the Stepped-CeO2(111) Surface by the Mars–van Krevelen Mechanism
Hyun You Kim,Graeme Henkelman +1 more
TL;DR: In this article, the Mars-van Krevelen (M-vK) mechanism was used to determine the rate of CO oxidation at nano-or meso-structured CeO2 found in industrial catalysts.

TL;DR: In this article, a CO-tolerant dense Pt single-atom catalysts were synthesized on an oxide support by manipulating the chemical nature of multi-component interfaces, and they were shown to be highly reactive for the CO oxidation reaction, which governs the key steps for chemical energy conversion and emission control.
