[36] Photocatalytic activity of nitrogen-doped TiO2 films under visible-light irradiation

*Sunyong Shim1, Kyosuke Ueda2, Takayuki Narushima2 (1. Graduate School of Engineering, Tohoku Univ. (M), 2. Graduate School of Engineering, Tohoku Univ.)

Keywords:反応性スパッタリング法、TiO2膜、光触媒、可視光応答化

酸素分圧と窒素分圧を変化させながら窒素添加TiO2膜を作製した。可視光照射下において、窒素添加TiO2膜は水接触角が10°付近まで減少した。メチルオレンジ濃度も時間とともに減少し、可視光応答の可能性を示した。
