Outline of Final Research Achievements

XAFS imaging techniques combining X-ray absorption fine structure and imaging techniques have been developed to visualize the spatial structures of heterogeneous catalysts. Scanning nano-XAFS using focused X-ray nanobeam was applied to Ce-Zr mixed oxide solid-solution particles for automobile exhausting processes. The distribution of Ce oxidation states in the Ce-Zr mixed oxide particles was imaged for their oxygen storage and release processes, showing different reaction modes for the oxygen storage and release processes. We also developed imaging XAFS using a zone plate and CT-XAFS and applied them to visualize the phase transitions of iron oxide crystals and the distribution of electrocatalysts.
