Research summary
Precise Synthesis of Metal Clusters and Metal Nanoparticles for Construction of Functional Materials and Catalyst Metal clusters and metal nanoparticles exhibit novel physicochemical properties and catalytic functions that are very different from those of the bulk state and strongly depend on their size and structure. Precise control of the size, surface, and electron state of metal clusters and metal nanoparticles are important for revealing their physicochemical properties and catalytic functions. In my studies, Metal clusters and metal nanoparticles are synthesized for construction of functional materials and catalyst.

Present specialized field
Nanostructural chemistry, Physical chemistry, Inorganic chemistry, Energy-related chemistry (Keyword：Metal Cluster, Nanoparticle, Catalyst, Functional Materials)
