Rationalizing Deactivation Behavior in Pyrochlore-Type CeO2-ZrO2 Oxygen Storage Catalysts

Chemistry Methods abstract image

We are excited to share that results from our collaboration with Toyota Motor Europe have been published in a new article in  Chemistry – Methods! “Rationalizing Deactivation Behavior in Pyrochlore-Type CeO2-ZrO2 Oxygen Storage Catalysts Using Multimodal Nano X-Ray Fluorescence Computed Tomography, X-Ray Diffraction Computed Tomography, and Scanning Three-Dimensional X-ray Diffraction

Using our unique multimodal characterisation tools, we analysed complex industrial catalysts across length scales from 0.15–500 µm. We uncovered structural changes — including a phase transformation from cation-ordered pyrochlore to fluorite across a wide range of length scales and a 25% loss in oxygen storage capacity — and linked them directly to catalytic performance. Nano-resolution proved essential to connect local structure with functionality, highlighting the value of advanced characterisation for real-world materials.
