| Outline of Final Research Achievements |
The purpose of this study is to visulaize gas molecules adsorbed on a ceramics-supporting fine metal particle surface, using the Reaction Science Ultra-High Voltage Scanning Transmission Electron Microscope in Nagoya University and to identify the reaction active site.
We applied an energy-filtering spectral imaging technique to Au-Ni bimetallic fine particles supported by SiO2 and were successful in visualizing NO and CO gas adsorption on their surface. In addition, we applied a multivariate analysis to the obtained data, resolving the spectrum of the gas molecules for identifying which gas specie is actually adsorbed. A research paper reporting the results above is now in preparation.
