AI 要約（直近 5 年の研究成果）

本研究室は、酸化物の化学還元を用いた新しい金属材料の合成法開発と、その触媒への応用に取り組んでいます。研究の中心は、融塩（塩の液体状態）という環境でカルシウム水化物などの強力な還元剤を使い、金属酸化物から金属やそれらの化合物を低温（600℃前後）で直接製造する方法です。この合成手法により、従来の方法では得られにくい、表面積の大きなナノ粒子やユニークな構造を持つ金属間化合物を効率的に製造できます。製造した金属材料の応用先として、有機化合物の水素化反応やアゾ染料などの環境汚染物質の分解に用いる触媒開発に注力しています。具体的には、複数の元素から成る高エントロピー合金や、複合金属間化合物などを合成し、それらが4-ニトロフェノールの還元やアルコール類の製造反応などにおいて優れた触媒性能を示すことを実証しています。環境汚染物質を分解する安価で安全な触媒の実現を目指す同時に、エネルギー効率や環境負荷の低い化学プロセスの構築に貢献する研究です。
