Researchers in South Korea have created a new type of electrode that captures carbon dioxide from exhaust gases and converts it directly into formic acid. The device works under realistic gas conditions, offering a practical step toward industrial carbon reuse. “This work shows that carbon capture and conversion do not need to be treated as separate steps. This configuration allows gas to pass through the electrode, trapping carbon dioxide and converting it simultaneously into formic acid. The technology is scalable and could reduce the complexity and cost of implementing CO₂ conversion in existing facilities.
