研究の背景 Background


Development of highly efficient functional materials in various fields such as energy storage and conversion, separation and purification of substances, and water purification is essential to realize a sustainable society. Performance of materials can be improved by controlling "nanostructures" and "nanospaces," which are the sites of transport, storage, and conversion. Thus, it is necessary to understand the phenomena occurring in nanostructures and nanospaces, and to provide feedback to material design.

研究の目標 Outcome

多孔質材料や層状化合物のナノ構造を制御した高機能な先端材料の開発を目指しています。これまでに、Metal-Organic Framework (MOF)を用いた光触媒材料や層状チタン酸ナトリウムを用いた環境浄化材料の開発を行ってきました(Fig. 1-3)。今後は、ナノ構造を高次制御した機能性材料の創製や新規機能の開拓を行い、触媒や水浄化などへの応用を目標としています。

This research aims to develop advanced materials by controlling the nanostructure of porous materials and layered materials. Recently I have developed photocatalytic materials based on Metal-Organic Frameworks (MOFs) and environmental purification materials based on layered sodium titanate. The goal of this research is the synthesis of functional materials with controlled nanostructures and the development of new functions for applications such as catalysts and water purification.
