Outline of Final Research Achievements

Gold clusters, which are smaller than 2 nm in diameter and less than 200 atoms, can be deposited on several metal oxides by Deposition-precipitation method followed by microwave drying instead of conventional oven drying at 120 °C and freeze drying. This method can be applied to metal oxides having different microwave absorption efficiencies. The obtained catalysts were tested in sulfide oxidation, CO oxidation, and oxidative esterification of aliphatic aldehyde. They exhibited high activities in both liquid and gas phase oxidation.
