Hierarchically Porous Fe–N–C Electrocatalysts with Accessible Fe-Nx Sites for High-Performance Oxygen Reduction Reaction in Zn-Air Batteries

Abstract Developing Fe–N–C electrocatalysts with high active site utilization remains a key challenge for the oxygen reduction reaction (ORR), primarily because of the limited accessibility of Fe-Nx sites. Herein, a hierarchically porous Fe–N–C (HP-Fe–N–C) catalyst is constructed...
