| Outline of Final Research Achievements |
We investigated the relationship of the atomic arrangement and the electronic structure of metal nanoparticles, nanostructures and oxide thin film materials with the functions and properties. After analyzing the average structure, local structure and electronic structure of nanometer-sized metal particles (Ru, Rh, Pd-Pt, Rh-Cu) with hydrogen storage characteristics and CO oxidation performance using synchrotron X-ray techniques, we discussed the correlation with the characteristic properties. Moreover, the electronic state was investigated also about the metal nanostructural materials. Furthermore, the structural order and the electronic state of the oxide thin films were examined, and the relationship with the optical characteristics was discussed. The utilized synchrotron X-ray techniques were high energy X-ray total scattering, Rietveld analysis, tpair distribution function, reverse Monte Carlo modeling, X-ray absorption fine structure, hard X-ray photoelectron spectroscopy.
