Overview
- The peer-reviewed study was published January 21 in ACS Energy Letters by a South Korea–based team with support from the National Research Foundation of Korea.
- The electrode stacks a CO2-capturing layer, a gas-permeable carbon paper sheet, and a tin(IV) oxide catalyst to capture and convert CO2 simultaneously.
- In tests with pure carbon dioxide, the system delivered roughly 40% higher efficiency than comparable electrodes.
- Under simulated flue gas containing 15% CO2, 8% oxygen, and 77% nitrogen, it continued producing significant amounts of formic acid while other systems underperformed.
- The device also functioned at CO2 levels similar to ambient air, though results are at laboratory scale and will require scale-up and field validation before industrial use.
