Research Area
- Contribution to the construction of a hydrogen society by using atomically precise metal clusters
Research Subjects
- Precise synthesis of ligand-protected metal clusters
- Activation of water-splitting photocatalysis by the use of atomically precise metal clusters
- Activation of fuel cell electrocatalysts by the use of atomically precise metal clusters
- Creation of atomically precise metal cluster-connected structures
Overview of Research
We have established techniques for the precise synthesis of metal clusters and their use to control the metal clusters on the supports with atomic precision. By using the obtained materials, the correlation between the number of atoms/chemical composition of the supported metal clusters in each material and the material function has been clarified with atomic precision, and through such research, clear design guidelines have been successfully obtained for the further enhancement of water splitting photocatalysis and fuel cells electrocatalysts in the future.
