Outline of Final Research Achievements

To realize artificial photosynthesis, strategic viewpoint of cross-fertilization based upon learning, mimicking, and exceeding natural photosynthesis was adopted in the project, where intensive studies has led to the stage with novel research viewpoints of 1) how could we get through the bottleneck subject, photon-flux-density problem of sun light, 2) how could we develop a protective environment of the artificial reaction center such as the protein environment in natural photosynthesis, and 3) how could we develop the system designed by both static viewpoint focusing on stable structures and dynamic one highlighting on reaction processes. Many innovative research results e.g. 1) development of chlorosome-type artificial light harvesting antenna system, 2) finding of two-electron oxidation of water, 3) development of artificial photosynthetic system with water and CO2 by visible light through Z-scheme, and 4) efficient photochemical reduction of CO2 have been successfully developed.
