Researchers at institutions reported via ScienceDaily introduced a three-layer electrode that captures CO2 from realistic exhaust streams and converts it directly into formic acid, featuring an integrated capture-and-conversion design. The device combines a CO2-adsorbing material, gas-permeable carbon paper and a tin(IV) oxide catalytic layer to let gas pass through while enabling electrochemical reduction to formic acid.
In laboratory testing "the electrode delivered roughly 40% higher efficiency than prior electrodes on pure CO2 and maintained strong production when exposed to simulated flue gas (15% CO2, 8% O2, 77% N2)." It also operated at ambient-level CO2, demonstrating potential for direct air or exhaust deployment. For consumers and industry this approach simplifies reuse pathways by eliminating a separate CO2 purification step and could lower costs for producing formic acid used in energy and manufacturing, aligning with trends toward circular carbon technologies.
