Description
Li-Ping Chi and co-authors turn carbon dioxide into formic acid inside an acidic reactor, a setting where the chemistry usually fails. Acid avoids the heavy carbon losses of alkaline setups, but hydrogen gas formation steals the current. Their design grows bismuth sheets upright on a gas layer, forming tiny pockets that act as reservoirs.
The pockets trap alkaline ions made during the reaction and keep protons out, so the surface stays locally alkaline even in acid. The reactor converted carbon dioxide to formic acid with over ninety-six percent efficiency at strong current. Run continuously for fifty hours, it stayed steady and made a pure acid solution. The authors offer the reservoir idea as a general fix for acid-based carbon conversion.
