PI message

In the research of inorganic materials, including functional ceramics, it is possible to create materials that exhibit various functions by combining several elements selected from a large number of elements. It is essential to control the synthesis process of these materials to synthesize materials in various forms. In our laboratory, we are working on low-temperature syntheses of oxides, nitrides, oxynitrides, sulfides, and inorganic-organic hybrids, with effective use of liquid phase in the synthesis process of ceramic materials. We are also actively engaged in joint research with various domestic and international research institutes and companies. In our research, we synthesize and evaluate new compounds with excellent properties with material and reaction design (we are beginning to incorporate computational chemistry). We also aim to control chemical reactions to synthesize various forms of inorganic materials suitable for the intended use. Developing a process that can be used anywhere without special equipment is one goal in our research.

 

Research

To fabricate highly functional ceramics that help to resolve environmental/energy issues, we effectively use the liquid phase, such as precursor solution and melt, in the synthetic process of ceramics to synthesize various forms of inorganic materials, including thin films, composites, sintered bodies, fine particles, and glasses that exhibit high functionality. We are studying the synthesis of inorganic materials for all-solid-state lithium secondary batteries, the development of electrochemical carbon dioxide or oxygen reduction catalysts, the application of layered double hydroxides in electrochemical devices, the development of new synthetic processes for oxides, halides, sulfides, and nitrides, and the elucidation of reaction mechanisms.
