Enhanced Oxygen Reduction Reaction Performance of Fe‐N 4 Single‐Atom Catalysts Through Fe 3 C Coupling
Understanding the electronic factors contributing to the high oxygen reduction reaction (ORR) activity of Fe‐N 4 sites remains a significant challenge due to the localized Fe 3d orbitals and their sensitivity to the coordination environment. In this study, we report an Fe‐based porous carbon catalyst (Fe 3 C@Fe...
