New Electrode Turns CO2 into Fuel
29 Jan
Summary
- New electrode captures CO2 and converts it to formic acid.
- System works effectively with simulated flue gas.
- It outperforms existing technologies in real-world conditions.

A groundbreaking electrode has been engineered to capture carbon dioxide (CO2) from exhaust gases and simultaneously convert it into formic acid. This dual-functionality electrode, detailed in ACS Energy Letters, represents a significant advancement in carbon capture and utilization.
The three-layer electrode comprises a CO2-capturing material, gas-permeable carbon paper, and a tin(IV) oxide catalytic layer. This design enables the direct transformation of captured CO2 into formic acid, a valuable chemical used in various industrial processes and fuel cells.
Testing revealed the new electrode's impressive efficiency, outperforming existing technologies by approximately 40% with pure CO gas. Its capabilities were further highlighted when tested with simulated flue gas, where it efficiently produced formic acid, unlike other systems.
