Near-ambient X-ray photoemission spectroscopy and kinetic approach to the mechanism of carbon monoxide oxidation over lanthanum substituted cobaltites
(Elsevier, 2009)
We have studied the oxidation of carbon monoxide over a lanthanum substituted perovskite (La0.5Sr0.5CoO3-d) catalyst prepared by spray pyrolysis. Under the assumption of a first-order kinetics mechanism for CO, it has been ...

Oxidation of CO over gold supported on Zn-modified ceria catalysts
(Elsevier, 2011)
A series of Zn-modified ceria solids were prepared by thermal decomposition of the corresponding metal propionates. The formation of segregated ZnO particles on the ceria surface is evidenced for these solids using X-ray ...

Low-temperature CO oxidation on multicomponent gold based catalysts
(Frontiers Media S.A, 2013)
In this work the development of gold catalysts, essentially based on γ-alumina with small superficial fraction of Ce-Fe mixed oxides as support for the low temperature CO oxidation is proposed. Characterization results ...

Fe-doped ceria solids synthesized by the microemulsion method for CO oxidation reactions
(Elsevier, 2011)
A series of Ce-Fe mixed oxides as well as the pure oxides were synthesized by the microemulsions method. The solid solution formation was established for all the Fe-doped systems and only a hardly noticeable segregation ...

Au/CeO2-ZnO/Al2O3 as Versatile Catalysts for Oxidation Reactions: Application in Gas/Liquid Environmental Processes
(Frontiers Media, 2019)
The present work showcases the versatility of nanogold systems supported on Zn-doped ceria when applied in two important environmental processes, the total CO oxidation, and the liquid phase oxidation of glucose to ...

Hydrothermal Synthesis and Characterization of Cu-MnOx Catalysts for CO Oxidation: Effect of Cu:Mn Molar Ratio on their Structure and Catalytic Activity
(Elsevier, 2023)
A comprehensive study was conducted on the synthesis of Cu-MnOx catalysts using a one-pot hydrothermal method followed by a calcination step. These catalysts were thoroughly characterized using techniques such as X-ray ...
