Tracking dynamic structural changes in catalysis by rapid 2D-XANES microscopy.

Abstract in brief

• The study introduces a high-speed 2D X-ray technique that captures real-time changes in catalyst structures, enabling detailed monitoring of processes like methane oxidation.
• Using this method, researchers observed how the chemical state of a PtAlO catalyst shifts dynamically during methane conversion, showcasing a reduction front moving through the material on a second time scale.
• This approach combines high spatial and temporal resolution with spectroscopic analysis, offering a powerful tool for studying fast chemical reactions in catalysts and other functional materials in real-world conditions.]
