The research team at Korea Energy Technology University (KENTECH), led by Professors Won Yong Choi and Myunghwan Oh, published their findings in ACS Energy Letters. Their three-layer electrode design integrates a porous carbon layer that selectively captures CO2, a tin oxide catalyst that converts it to formic acid, and carbon paper that manages gas flow and electron transfer.
Perhaps most remarkably, the electrode functions at CO2 concentrations as low as four hundred parts per million, roughly equivalent to atmospheric levels. In tests with pure CO2, the new design outperformed existing carbon-converting electrodes by approximately forty percent.

Researchers at Korea Energy Technology University have developed a revolutionary three-layer electrode that captures carbon dioxide directly from industrial exhaust and converts it into formic acid in a single step. The breakthrough eliminates the need for expensive CO2 purification, potentially transforming how factories manage their emissions.
A Game-Changing Approach to Carbon Capture
Scientists in South Korea have unveiled a new electrode technology that could fundamentally change how industries deal with their carbon dioxide emissions. Rather than treating carbon capture and conversion as separate, costly processes, this innovation combines both functions into one elegant device.The research team at Korea Energy Technology University (KENTECH), led by Professors Won Yong Choi and Myunghwan Oh, published their findings in ACS Energy Letters. Their three-layer electrode design integrates a porous carbon layer that selectively captures CO2, a tin oxide catalyst that converts it to formic acid, and carbon paper that manages gas flow and electron transfer.
Real-World Performance
Unlike many laboratory breakthroughs that only work with purified gases, this electrode was specifically designed for real industrial conditions. When tested with simulated flue gas containing just fifteen percent CO2 mixed with oxygen and nitrogen, the device continued producing substantial amounts of formic acid, while competing technologies essentially stopped working.Perhaps most remarkably, the electrode functions at CO2 concentrations as low as four hundred parts per million, roughly equivalent to atmospheric levels. In tests with pure CO2, the new design outperformed existing carbon-converting electrodes by approximately forty percent.
Why Formic Acid Matters
Formic acid is not just an industrial chemical. It is increasingly viewed as a promising hydrogen energy carrier for fuel cells. One litre of formic acid can yield nearly six hundred litres of hydrogen, and unlike pure hydrogen, formic acid is a stable liquid that can be safely stored and transported at room temperature. This makes it an attractive option for long-term storage of renewable energy.Future Implications
The KENTECH team believes their approach could open pathways for integrating carbon capture into practical industrial applications. They are already exploring whether similar systems could target other greenhouse gases such as methane, potentially offering a scalable solution to multiple climate challenges.Published January 31, 2026 at 8:15am
