Oxygen evolution reaction (OER) demands cost‐effective electrocatalysts with high catalytic performance. In this effort, metal–organic framework (MOF)‐derived nanocomposites are presenting promising prospects to achieve this goal. Herein, FeCo bimetallic MOFs with different compositions are prepared through a sodium hydroxide assisted approach. By means of a successive carbonization and phosphating reaction, a series of MOF‐derived multicomponent products are synthesized. The resultant P‐doped products present enhance electrocatalytic performance for OER in alkaline electrolyte in comparison with a commercial RuO₂ catalyst, which paves the way for their practical applications for water splitting. The developed method herein also offers an opportunity for the large‐scale preparation of MOF‐derived product toward energy conversion applications.

MOF衍生的双金属FeCo-P / C纳米复合材料是氧释放反应的高效催化剂

氧气析出反应（OER）需要具有高催化性能的经济高效的电催化剂。在这项工作中，金属有机框架（MOF）衍生的纳米复合材料为实现该目标提供了有希望的前景。在此，通过氢氧化钠辅助法制备了具有不同组成的FeCo双金属MOF。通过连续的碳化和磷化反应，合成了一系列MOF衍生的多组分产品。与市售RuO ₂相比，所得的P掺杂产物增强了OER在碱性电解质中的电催化性能。催化剂，为水分解的实际应用铺平了道路。本文中开发的方法还为大规模制备MOF衍生产品提供了机会，可用于能量转换应用。
