| Outline of Final Research Achievements |
The synthesis of supported metal cluster catalysts with atomic precision is essential for their catalytic application because metal clusters consisting of less than 100 atoms show size-specific catalysis. In this project, we developed a new synthesis method of atomically precise gold cluster catalysts protected by metal oxide shell by the use of thiolate-protected gold cluster as a template. First, we synthesized Au25(SR)18 cluster with OH function group in the ligand. The metal oxide-protected gold cluster catalyst was synthesized by the reaction of metal oxide precussor with -OH functional group of the cluster by sol-gel method and following heat treatment to remove the thiolate ligands. We successfully synthesized the metal oxide-protected gold clusters without aggregation. Finally,we applied the metal oxide protected gold cluster catalysts for the hydrogenation of nitro phenol. We found the support affected the catalytic activities.
