Abstract Manipulating the coordination environment and electron distribution for heterogeneous catalysts at atomic level is an effective strategy to improve electrocatalytic performance but remains challenging. Herein, atomically dispersed Fe Co anchored on nitrogen, phosphorus co‐doped carbon hollow nanorod structures (FeCo‐NPC) are rationally designed synthesized. The as‐prepared FeCo‐NPC catalyst exhibits significantly boosted kinetics greatly upshifts half‐wave potential oxygen reduction reaction. Furthermore, when utilized as cathode, also displays excellent zinc‐air battery performance. Experimental theoretical results demonstrate that introduction of single atoms with Co‐N/P around isolated induces asymmetric distribution, resulting in suitable adsorption/desorption ability intermediates optimized reaction barrier, thereby improving activity.
