In this work, we reported the synthesis of a novel electro‐catalyst composed of Fe and Co bimetallic nanoalloys embedded in N‐enriched carbon framework (FeCo@NC) for oxygen reduction reaction. The FeCo@NC was synthesized through pyrolyzing a dual metal‐organic framework (MOF) under argon atmosphere. This FeCo@NC electrocatalyst showed remarkable performance towards ORR with a high half‐wave potential of 0.827 V versus reversible hydrogen potential (RHE), which was comparable to the state‐of‐the‐art commercial Pt/C catalyst. The enhanced activity could be ascribed to the large specific surface area, the abundant active sites and the synergistic effect of bimetallic alloy.
