摘要：
高活性MOF基催化剂的设计和合成为促进动力学不利的氧还原反应（ORR）过程开辟了新的途径.本研究通过在ZIF-8前驱体表面涂覆二茂铁甲酸,然后进行两步炭化工艺,设计和制备了一种具有新型结构的高效电催化剂,以提高ORR性能.两步炭化过程对于将热解Fe3C纳米颗粒封装到碳纳米管（CNTs）中以及将Fe单原子隔离到N掺杂碳（NC）基体上至关重要.此外, Fe元素的相对含量对优化催化剂的ORR性能至关重要.所制得Fe3C@CNTs/NC-M催化剂结构先进,在碱性溶液中表现出良好的长期稳定性和电催化ORR性能,其半波电位和极限电流分别达到0.941 V和6.31 mA cm-2.此外,该电催化剂在甲醇溶液中具有较强的耐受性和良好的稳定性. Fe3C@CNTs/NC-M锌空气电池（ZAB）具有1.525 V的开路电位, 420 mA cm-2时的峰值功率密度为348 mW cm-2,10 mA cm-2时的最大容量为843 mA h gZn-1.因此,这种合成策略为构建具有有效和稳定的ORR性能的MOF基电催化材料提供了一条有效途径.
