A team of Japanese chemists has found a way to turn CO2 into formic acid, which – aside from being a useful cleaning agent and preservative – is a key chemical ingredient in a vast array of reactions. Formic acid also appears frequently in nature, most notably in ant and bee venom. And, most recently, it’s drawn attention as a possible way to transport hydrogen fuel.

The new method relies on the concept of “photoreduction”: using light to provide energy for CO2 to react with something which contains hydrogen, allowing it to become formic acid (CH2O2, often written as HCOOH).
