Outline of Final Research Achievements

Anisotropic gold nanocrystals are attractive because of their potentials for novel optical and catalytic properties. We prepared anisotropic gold nanoflowers and bimetallic nanoflowers, such as gold-silver and gold-palladium, and used these nanoflowers for aerobic oxidation of 1-phenylethyl alcohol. The nanoflower structure is very effective for increasing the acetophenone-formation rate due to its larger surface area, and the presence of Au atoms at its corners and edges. In addition, catalytic activity of bimetallic nanoflowers is higher than that of gold nanoflowers due to increases in the electron densities of the Au atoms. The findings in this research will open new possibilities of bimetallic anisotropic nanocrystals as novel metal catalysts.
