Research Abstract	近年、酸化チタン光触媒を有害物質を含む汚染水処理や超純水の製造に応用する研究が活発である。しかし、光触媒反応の多くは粉末状の微粒子光触媒を用いた懸濁系液相反応で行われているため、反応後に光触媒を回収することが極めて困難である。このため、光触媒プロセスの実用化には液層からの分離回収・再使用に適した形態の酸化チタン光触媒を設計することが必須である。また、光触媒活性は触媒の表面結晶構造や触媒活性点の局所構造に大きく依存するため、高効率な光触媒の調製には表面構造の精密制御が望まれる。本研究では、触媒調製法として新規なイオン工学的技法を駆使し、実用に適した形態を有する薄膜状酸化チタン光触媒を調製するとともに、イオン注入法の適用により可視光応答型の酸化チタン薄膜光触媒の調製を目指した。本研究では、クラスターイオンビーム法を用いることでポーラスバイコールガラス上に膜厚を任意に制御した均一かつ透明な薄膜状の酸化チタン光触媒の調製に成功した。UV-VISおよびXAFS測定により、膜厚が300nm以下の極めて薄い試料においても結晶性の高いアナタース型の酸化チタン層の形成が確認された。この薄膜酸化チタン光触媒は紫外光(λ>270nm)照射下でNOをN_2とO_2およびN_2Oに光触媒的に分解した。さらに、イオン注入法により、薄膜酸化チタン光触媒に極微少量のCrやVなどの遷移金属イオンを注入することで、可視光を吸収し可視光照射下でNOを分解する第2世代の薄膜酸化チタン光触媒の創製に成功した。さらに、可視光照射下で最も高活性を与えるイオン注入条件を検討し、注入金属イオン種(Cr,V)、注入量(3X10^<16> N・cm^<-2>)および注入エネルギー(150 KeV)などの最適値を得た。これらの成果は、21世紀に向けその大規模な応用・製品化が期待されている可視光で機能する酸化チタン薄膜光触媒の開発を世界に先駆けて行ったもので、きわめて大きな波及効果が期待できるものである。
