Abstract

Abstract: 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. Abstract : Unique nano hierarchical structures with large specific surface encapsulated in highly nitrogen doped carbon layers were synthesized by pyrolysis of bimetallic‐MOF precursors, serving as novel excellent oxygen catalysts towards ORR.
