Cobalt iron carbonate hydroxide hydrate on 3D porous carbon as active and stable bifunctional oxygen electrode for Zn–air battery

We report cobalt iron carbonate hydroxide hydrate on three-dimensions porous carbon as active and stable bifunctional oxygen electrode for Zn–air battery. The difference between oxygen evolution reaction potential at 10 mA cm−2 and oxygen reduction reaction half-wave potential is only 0.804 V, outpe...

We report cobalt iron carbonate hydroxide hydrate on three-dimensions porous carbon as active and stable bifunctional oxygen electrode for Zn–air battery. The difference between oxygen evolution reaction potential at 10 mA cm−2 and oxygen reduction reaction half-wave potential is only 0.804 V, outperforming most catalysts reported to date. The cobalt iron carbonate hydroxide hydrate on porous carbon serves as a superb air cathode electrocatalyst in high-performance rechargeable Zn–air battery. Ausführliche Beschreibung
