当研究室は、触媒を用いた環境浄化と化学物質の変換・合成に関する研究を行っています。特に、自動車排ガスや産業排ガス中の窒素酸化物や一酸化炭素の低温除去、メタンの燃焼、および二酸化炭素の有効利用といった現代的な課題に取り組んでいます。ゼオライトと呼ばれる多孔性固体材料に金属を導入した触媒や、酸性を持つ固体材料を中心に研究対象としており、これらの材料がどのような構造を持ち、どのように反応を促進するかを解明することを目指しています。研究の手法としては、計算化学と実験を組み合わせたアプローチを採用しています。自動反応経路探索という計算手法を用いて、触媒表面での反応メカニズムを理論的に予測し、赤外分光やX線吸収分光などの分析手法を用いて実際の触媒動作を可視化・検証しています。このように計算と実験を相互に活用することで、既存触媒の性能向上や新しい触媒材料の設計に向けた知見を得ています。これまでの研究から、ゼオライトの細孔構造や酸性サイトが触媒活性に大きく影響すること、また複数の活性点が協働して反応を進める場合があることが明らかになっています。こうした知見に基づき、当研究室では環境負荷の低減と資源有効利用を実現する高性能触媒の開発に貢献しています。
