Contribution of cerium/zirconium mixed oxides to the activity of a new generation of TWC
Juan R. González-Velasco,Miguel A. Gutiérrez-Ortiz,Jean-Louis Marc,Juan Ángel Botas,M. Pilar González-Marcos,Gilbert Blanchard +5 more
TL;DR: In this article, the catalytic activity of several cerium/zirconium mixed oxides for TWC applications has been investigated with the aim of optimising the Ce/Zr composition.

NOx storage on barium-containing three-way catalyst in the presence of CO2
TL;DR: In this article, the authors compared the NOx trapping capability of three-way catalysts (4, 9 and 9 wt% Ba-containing three way catalysts) compared to that of bulk carbonate and alumina-supported barium carbonate from Rhodia using infrared spectroscopy, X-ray diffraction and EDX.

Surface FTIR investigations on CexZr1−xO2 system
TL;DR: In this paper, a surface study of the Ce x Zr 1-x O 2 system was performed by Fourier transform infrared spectroscopy and using several probe molecules, the authors tried to characterize surface sites (OH and methanol), acid (CO and pyridine) and basic (CO 2 ) properties of different compositions of the solid solution.

Evidence of a lacunar mechanism for deNOx activity in ceria-based catalysts
Marco Daturi,Nicolas Bion,J. Saussey,Jean-Claude Lavalley,C. Hedouin,Thierry Seguelong,Gilbert Blanchard +6 more
TL;DR: Using in situ FTIR spectroscopy and mass spectrometry, it has been demonstrated that deNOx activity in oxide-based catalysts such as ceria can be correlated to the amount of oxygen vacancies present on the surface of the material as discussed by the authors.

Operando FTIR study of NOx storage over a Pt/K/Mn/Al2O3-CeO2 catalyst
TL;DR: In this article, the storage of NOx under lean conditions has been studied for a Pt/K/Mn/Al2O3-CeO2 catalyst by operando FTIR spectroscopy.
