Five-metal 2D catalysts could convert CO₂ to CO without needing an extra electrical boost

Carbon dioxide (CO₂) is usually discussed as something the world needs to get rid of. Activities such as the burning of fossil fuels for daily use, including electricity and transportation, and industrial applications release significant amounts of CO₂, and the gas enters the atmosphere. Researchers are now asking whether this road could have a roundabout. What if CO₂, which is at the center of the climate crisis, could be turned into something useful and put back into the industrial cycle?
