| Outline of Final Research Achievements |
Based on single-site photocatalysts (isolated four-coordinated oxide species, photofunctional metal complex) prepared in pore space and framework using nanoporous materials such as zeolite, mesoporous silica and metal organic frameworks (MOF). We have developed environmentally-friendly functional materials such as visible light responsive photocatalysts with high activity and high selectivity, plasmonic metal nanocatalysts, and superhydrophilic superhydrophobic thin films. By controlling the pore structure and surface chemistry, we have made it possible to improve the efficiency of hydrogen production and one-pot reaction.

ナノ多孔体に組込んだ「シングルサイト光触媒」の特異な局所構造と光触媒特性に注目し、従来の半導体光触媒と全く異なる励起構造と反応特性を見出す先駆的な成果を挙げた。さらに、シングルサイト光触媒を基盤として「ものづくり」に応用し、可視光応答性光触媒、プラズモニック金属ナノ触媒、超親水性超撥水性薄膜、などの機能性材料を開発し、多くの触媒開発(錯体化学を含む)へ有用な指針を示すことができた。
