A Japanese research group saw its way clear to the practical application of ruthenium-rhenium (Ru-Re) supramolecular complex as a photocatalyst that uses sunlight to reduce CO2 to CO, which can be used as a chemical engineering material.
The group is led by Osamu Ishitani, professor at the Graduate School of Science and Engineering of the Tokyo Institute of Technology. It combined the Re complex, which can efficiently reduce CO2, with the Ru complex, which can absorb light (photon) in the visible region of the sunlight spectrum, in a sophisticated manner.
