Aqueous zinc-air batteries provide a possibility to replace fossil fuels. However, developing bi-functional electrocatalysts with high activity, low-cost and environmental friendliness for zinc-air batteries remains a challenge. In this work, we report an efficient bifunctional electrocatalyst (H-CoP@NC) that is fabricated by phosphating a hollow metal organic framework (MOF) prepared using a self-template method. The H-CoP@NC exhibits a halfwave potential of 0.81V (vs. RHE) for the oxygen reduction reaction (ORR), and an overpotential of 390 mV for the oxygen evolution reaction (OER) at a cur...
