Executive Summary
Researchers built a gas-permeable electrode that captures dilute CO2 from exhaust or air and converts it into formic acid
- A three-layer gas-permeable electrode captures CO2 and converts it directly to formic acid
- The design combines CO2 capture material carbon paper and tin(IV) oxide catalyst
- It worked with simulated flue gas containing 15% CO2 8% O2 and 77% N2
- The system also operated at CO2 levels similar to normal air
- Compared with existing electrodes it showed about 40% higher efficiency in pure CO2 tests
- Formic acid is a useful chemical for fuel cells and industrial processes
- The work was funded by the National Research Foundation of Korea
Quick Facts
- What: Built an electrode that turns dilute CO2 into formic acid
- Where: Reported in ACS Energy Letters from Korea
- Why: To make carbon capture and reuse simpler and more practical
- Who: Researchers led by Donglai Pan and Wonyong Choi
- When: Published in 2026
