Oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are generally catalyzed by precious metals (Pt) and metal oxides (IrO₂) which still have many shortages including expensive price, poor selectivity and undesirable stability. In this work, we report a Mn⁰-doped CoN_x on N-doped porous carbon (Mn-CoN_x/N-PC) composite from carbonizing metal-organic framework (MOF) derivative as the dual-functional catalyst to boost both the ORR and OER performances. Owing to the strong coordination effect between nitrogen and metal elements, the introduction of N can obviously improve the content of Co-N-C active sites for ORR. Meanwhile, the Mn-doping significantly regulates the electronic structure of the Co element and increases the content of Co⁰ which provide efficient OER active sites. Mn-CoN_x/N-PC catalyst delivers super dual-functional activity with a half-wave potential of 0.85 V, better than the 20% Pt/C catalyst (0.82 V). When used in Zn-air batteries for testing, Mn-CoN_x/N-PC electrocatalyst shows a high power density (145 mW·cm⁻²) and good cycle performance.

氧还原反应（ORR）和析氧反应（OER）通常由贵金属（Pt）和金属氧化物（IrO ₂）催化，但仍存在价格昂贵、选择性差和稳定性差等诸多不足。在这项工作中，我们报告一个锰⁰掺杂的CoN _X上N掺杂多孔碳（MN-CON _X/N-PC) 复合材料来自碳化金属有机骨架 (MOF) 衍生物作为双功能催化剂，以提高 ORR 和 OER 性能。由于氮和金属元素之间的强配位作用，N的引入可以明显提高ORR的Co-NC活性位点的含量。同时，Mn掺杂显着调节了Co元素的电子结构并增加了Co ⁰的含量，从而提供了有效的OER活性位点。Mn-CoN _x /N-PC 催化剂具有超强的双功能活性，半波电位为 0.85 V，优于 20% Pt/C 催化剂 (0.82 V)。当用于锌空气电池进行测试时，Mn-CoN _x /N-PC 电催化剂显示出高功率密度（145 mW·cm ^-2) 和良好的循环性能。
