| Outline of Final Research Achievements |
To increase the performance of photo-induced reduction catalyst contributing to green technology, it was investigated to combine nano-particles with different functions; carbon dioxide adsorption materials and photo-induced reduction catalyst. In this research, K-Al composite oxide and strontium titanate was used respectively. In addition, the relationship between "photocatalytic reduction ability" and "carrier life time" was considered from the measurement results using the "microwave photoconductivity decay method". In the future, we will advance the elucidation of the phenomenon at the related phase interface in more detail.

| Academic Significance and Societal Importance of the Research Achievements |
太陽光利用を想定した大気中CO2の光触媒還元固定化は人工光合成型反応として注目されいるが、メタンやメタノールのようなより付加価値の高い炭化水素への物質変換が高効率で実現するためには、CO2の活性化過程を促進する高機能光触媒の開発が望まれる。これに対し、物理化学的な視点から性能向上に取り組み、電子寿命と光触媒活性の間の学理の追求を深め、関連する相界面の現象メカニズム解明できることに意義を有する。
