Solar Fuels -CO2 Photoconversion into Organic Compounds

We succeeded in the artificial photosynthesis that generates organic compounds, formic acid, from water and carbon dioxide using solar light without external energy and/or material sources, for the first time in the world.
This is a combination of two chemical reactions driven by solar energy, which are (1) extraction of electrons by H2O oxidation and (2) reduction of CO2 to convert it into organic compounds. We have newly developed the hybrid-photocatalyst for CO2 reduction, which was composed of a semiconductor and metal complexes. The hybrid-photocatalyst was wired with another semiconductor, which is capable of H2O oxidation. Our technology made a big leap for artificial photosynthesis, and it would be one of the key technologies for future carbon-neutral society.
