Outline of Final Research Achievements |
①Using high-voltage transmission electron microscope (TEM) equipped with a gas environmental cell for in-situ observation, we have observed changing nano structure of nanoporous Au at atomic scale, and found that surface diffusion was the major degradation factor. The plane defects such as twins were found to be effective to suppress the surface diffusion. ②By selective etching Mn from a CuNiMn solid-solution alloy, we have developed advanced exhaust-gas catalysts without noble metals and rare-earth elements. The microstructure showed unique nano-architectures that are durable against long-term duration test at high temperature. The in-situ TEM successfully captured microstucture changes induced by NO reduction reaction.
