Outline of Final Research Achievements

Selective oxidation of organic materials for the synthesis of fine chemicals and pharmaceuticals has received much attention in chemical research. In particular, selective oxidation using a semiconductor photocatalyst under visible-light irradiation will be one of the breakthrough technologies for sustainable energy conversion process. However, the famous semiconductor photocatalyst, such as TiO2, has the following drawbacks; low photoactivity, poor selectivity and lack of utilization of visible light, and therefore hinder its application. Here, we attempted to examine photocatalytic selective oxidation of organic materials, using metal doped SrTiO3 as a visible light responsible photocatalyst.

Academic Significance and Societal Importance of the Research Achievements

クリーンなエネルギー源である太陽光を利用した有機変換反応は，環境調和の観点から，持続可能な物質変換プロセスの実現に向けて重要な触媒技術の一つである．特に，太陽光に多く含まれる可視光に応答する半導体光触媒を用いた有機変換反応は，既存の固体触媒や電解触媒を利用したプロセスに比べて，厳しい反応条件や危険な試薬，電力を必要としない低環境負荷なプロセスである．
本研究では、数ある有機変換反応の中で，薬品や香料の合成プロセスの起点となる重要な反応を，可視光応答型の光触媒を用いて実現することができた．
