| Outline of Final Research Achievements |
We have developed XAFS-spectroscopy-imaging techniques combining hard X-ray imaging techniques and X-ray Absorption Fine Structure (spectroscopy) for the visualization of spatial element information inside solid materials. XAFS imaging provides spatial distribution of each element, oxidation state, local coordination structure inside solid particles and crystals and we visualized the reaction diffusions inside mixed oxides and solid catalysts by the XAFS imaging techniques. We succeeded in visualizing the oxidation reaction track inside ceria-zirconia solid-solution materials and redox reaction behaviors of Cr-doped iron oxide crystals for the first time.
