摘要：

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.
