Abstract Single‐atom catalysts (SACs) with edge‐located metal active sites exhibit superior oxygen reduction reaction (ORR) performance due to their narrower energy gap and higher electron density. However, controllably designing such fully reveal advantages remains challenging. Herein, rich Fe‐N 4 anchored in hierarchically porous carbon nanofibers (denoted as e 1 ‐Fe‐N‐C) are fabricated via an situ zinc‐assisted thermal etching strategy. The ‐Fe‐N‐C catalyst demonstrates alkaline ORR activity compared counterparts fewer commercial Pt/C. Density functional theory calculations show that the accumulation of more negative charges near formation partially reduced Fe state reduce barrier for process. Additionally, unique structures mesopores macropores facilitate full utilization enhance long‐range mass transfer. zinc–air battery (ZAB) assembled has a peak power density 198.9 mW cm −2 , Pt/C (152.3 ). present strategy by facile controlling amount zinc acetate template systematically superiority sites, providing new design avenue rational defect engineering achieve high‐performance ORR.
