# CO2 Conversion Devices A Three-Layer Electrode Turns Exhaust into Formic Acid By Debra John | Written with AI assistance | Published 2026-02-05 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/threelayer-electrode References: [sciencedaily](https://www.sciencedaily.com/releases/2026/01/260128230509.htm)  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](https://www.trendhunter.com/trends/birdie-20), gas-permeable carbon paper and a tin(IV) oxide catalytic layer to let gas pass through while enabling [electrochemical reduction to formic acid](https://www.trendhunter.com/trends/newtrace-voltagen). 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](https://www.trendhunter.com/trends/codegig-carbon).
