A brief excerpt:
"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 technologies to capture, and profitably use, Carbon Dioxide are being developed and implemented worldwide. Moreover, those technologies are being refined and advanced to make them more efficient, to reduce the energy inputs needed to accomplish them. CO2 is becoming what it should be: A valuable by-product of coal use.
