| Research Abstract |
The effect of size in the aerobic oxidation catalysis of Au clusters stabilized by PVP has been investigated in the atomic resolution. It is concluded that (1) only the Au clusters smaller than 70-mer are active in the catalysis and (2) the activity is originated from the excess negative charge on the Au clusters which is donated by PVP. It was found that the microwave irradiation drastically accelerates the aerobic oxidation catalysis of Au11 supported on mesoporus silica.
