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.
The electrode also proved effective at capturing CO2 at atmospheric concentrations, indicating its potential for real-world applications. Researchers suggest this design could be adapted for capturing and converting other greenhouse gases, offering a promising path for industrial carbon management.
