Research Abstract |
Catalytic properties such as activity and selectivity of oxide-supported metal catalysts strongly depend on metal cluster size and metal-support interaction. In this research project, we tried to develop a method to prepare gold clusters with a small size distribution in the range of single atom-10 nm on a titanium dioxide single crystal surface by using ligand-protected gold clusters, and the structures of the deposited gold clusters were examined at the atomic level by surface science techniques such as STM/AFM and polarization dependent total-reflection fluorescence XAFS. We also developed a ultra-high vacuum equipment for measuring catalytic activity of the deposited gold clusters formed on an oxide single crystal surface.
