1) Development of new catalysts|
Catalysts are indispensable for many chemical reactions, and solid catalysts areespecially convenient because separation of products can be easily achieved and because it is possible to reuse solid catalysts. For the purpose of converting inactive molecules to useful products, we are developing new solid catalysts based on metal clusters, metal complexes and metal ion-containing ionic liquids.
2) Study on photo-induced processes
Photo-induced chemical reactions are important as a fundamental method for chemical conversion, as well as chemical evolution in relation to cosmochemistry. We are studying organic photochemical reactions and photo-induced processes on ice.
3) Chemical processes on solid surfaces
We are investigating chemical processes on solid surfaces of metals and semiconductors using High Resolution Electron Energy Loss Spectroscopy, Electron Stimulated Desorption, Mass spectrometry, Scanning Probe Microscopy and so on. Computational methods such as Density Functional Theory and Monte Carlo simulations are also adopted to explore reaction mechanisms and structural information for intermediate species.

We are aiming at the integration of theory, synthesis and functions for metal and metal oxide clusters, which will be useful for understanding existing materials and designing new materials with desirable functions.
