Outline of Research at the Start

金属錯体と半導体の異種の光触媒から成る集積型の光反応デバイスを、光電気化学的手法を用いたボトムアップ型アプローチによって開発する。還元・酸化それぞれの目的反応に即した反応場を光触媒電極として個別に開発し、設計指針を確立する。更にそれらを集積化することで、光のエネルギーのみを用いたエネルギー蓄積型のグリーンな反応を効率的に駆動する自立型人工光合成系を創出する。

Outline of Final Research Achievements

Integrated photocatalytic systems consisting of metal complex and semiconductor photocatalysts have been developed to realize highly functional artificial photosynthesis reactions by a bottom-up approach using a photoelectrochemical method. The photocatalysts were divided into the electrodes on the reducing side and the oxidizing side, and the design study was conducted to improve their activities based on photoelectrochemical measurements. The construction of the stand-alone photocatalytic systems with the activity for artificial photosynthetic reactions was achieved by integrating the knowledge of two types of photocatalysts developed individually into one hybridized component.

Academic Significance and Societal Importance of the Research Achievements

金属錯体と半導体の異種の光触媒能を組み合わせることで、エネルギー蓄積型の化学反応(人工光合成反応)を光のエネルギーのみで進行させる系の高機能な構築が期待される。本研究では、それぞれの光触媒を別個に電極化して光電気化学を用いて解析することで、複雑な系の中での要素ごとの高活性化・高機能化を目指した。個々において得た設計指針を基に、これを一つの複合体へと集積化するボトムアップ手法を用いて、実際に目的の反応を駆動可能な系を開発した。
