| Outline of Final Research Achievements |
We succeeded in developing a new photosensitizer that can utilize all visible light. We clarified the factors that determine the efficiency of the production of one-electron reduced photosensitizers via the reaction of the excited photosensitizers with reductant. The reaction mechanisms of the entire processes of CO2 photocatalytic reduction using Re complex catalysts were clarified.
We could demonstrate that the supramolecular photocatalysts reduce CO2 efficiently even on solid surface. By addition of photosensitizers around the supramolecular photocatalyst, the photocatalytic stability of the supramolecular photocatalysts on the surface were drastically improved. We have succeeded in photocatalytically producing CO, formic acid and hydroperoxide using only water, CO2 and visible light. Hybrid photocatalyst consisting of the supramolecular photocatalyst and conjugated polymer showed the highest CO2 reduction photocatalysis compared to any reported CO2 reduction photocatalytic systems.
