Characterization of SO2-poisoned ceria-zirconia mixed oxides

Applied Catalysis B: Environmental, 2004
Abstract CeO2, ZrO2, and a series of CexZr1−xO2 catalysts with 1 wt.% Pd were exposed to fixed exposures of SO2 under oxidizing environments and then characterized by FTIR, pulse–reactor studies with CO and O2, and temperature-programmed desorption (TPD).

Structural Determination, Oxygen Diffusion, and Storage Capacity of a High‐Entropy Fluorite‐Type Oxidation Catalyst

Small Structures, Volume 7, Issue 3, March 2026.
Inducing cationic high entropy on CeO2 modifies the structure, leading to increased oxygen diffusion and resistance to sintering. In turn, this leads to enhanced oxygen storage capacities without degradation, showing potential for oxidation catalysis.

Tetravalent doping of CeO2 : the impact of valence electron character on group IV dopant influence [PDF]

, 2013
Fluorite CeO2 doped with group IV elements is studied within the density functional theory (DFT) and DFT + U framework. Concentration-dependent formation energies are calculated for Ce(1-x)Z(x)O(2) (Z = C, Si, Ge, Sn, Pb, Ti, Zr, Hf) with 0

Universal In Situ Isotope Exchange Raman Spectroscopy (IERS) Methodology for Measuring Oxygen Surface Exchange Dynamics Using a Probe Layer

Advanced Functional Materials, Volume 36, Issue 17, 26 February 2026.
A bespoke multilayer thin film configuration has been designed, which overcomes the material dependency of conventional isotope exchange Raman spectroscopy (IERS). This universal IERS methodology is efficient, non‐destructive and provides additional structural information and time resolution, which can be further extended to various isotopic elements ...

Ceria-Praseodymia Mixed Oxides: Relationships Between Redox Properties and Catalytic Activities Towards NO Oxidation to NO2 and CO-PROX Reactions [PDF]

, 2016
A series of CexPr1−xO2−δ catalysts was prepared by co-precipitation method in alkali media. These catalysts were characterized by N2 adsorption–desorption isotherms at −196 °C, X-ray diffraction, thermogravimetry combined with mass spectrometry (TG-MS ...

Impact Resistance of Yttria- and Ceria-Doped Zirconia Ceramics in Relation to Their Tetragonal-to-Monoclinic Transformation Ability

Ceramics
In this work, the impact resistance of three zirconia ceramics was investigated: two yttria-stabilized zirconia (3Y-TZP and 1.5Y-TZP) and a ceria-stabilized-zirconia (Ce-TZP) composite.

Ceria Zirconia Mixed Oxides Prepared by Hydrothermal Templating Method for the Oxidation of Ethyl Benzene

Bulletin of Chemical Reaction Engineering & Catalysis, 2013
CeO2–ZrO2 oxides were prepared by the surfactant-templated method using cetyl trimethyl ammonium bromide (CTAB) as template. These were characterized by XRD, FT-IR, TEM, SEM, BET and TPD-CO2.
