| Outline of Final Research Achievements |
In this study, we newly developed two kinds of imaging-XAFS techniques; two-dimensional scanning XAFS technique (Nano-XAFS) and CT-XAFS technique combined with 3D-computed tomography (CT) method. The developed XAFS imaging techniques were applied for the operando characterization while the practical catalyst materials were reacted or operated. Through the investigation for the reaction and degradation processes in a polymer electrolyte fuel cell (PEFC) catalyst membrane and practical catalyst particles, we clarified the details of interaction among the structure, chemical state, and their properties in the view of two/three-dimensional visualizations.
