| Outline of Final Research Achievements |
Hybrid photocatalysts that consist of ruthenium complex and organic semiconductor carbon nitride are capable of reducing carbon dioxide into formic acid upon visible light. This research project aimed at improving the efficiency of the hybrid system by refining both the metal complex and the semiconductor parts, as well as controlling the product distribution of carbon dioxide reduction. Modification of carbon nitride nanosheets with silver nanoparticles resulted in significant enhancement of efficiency of carbon dioxide reduction in ruthenium-complex/carbon nitride hybrid system. Regarding the control of the product distribution, selective carbon monoxide formation was realized by changing metal complex from previously reported ruthenium to ruthenium-rhenium binuclear complex (or iron complex).
