Scientists have synthesized a compound with 3 ruthenium atoms connected by an organic molecule that absorbs near-infrared light to produce hydrogen from water. The absorbed light stimulates electrons to ‘jump’ into orbitals that do not exist in other, similar compounds. This is the first successful use of infrared light to reduce water into hydrogen, which can be used for energy conversion and storage, and other industrial purposes in a future sustainable energy society.
Solar cells must absorb light of particular wavelengths, depending on how much energy the cell needs to drive the reaction...
