Abstract Rational design of non‐noble materials as highly efficient, economical, and durable bifunctional catalysts for oxygen evolution reduction reactions (OER/ORR) is currently a critical obstacle rechargeable metal‐air batteries. A new route involving S was developed to achieve atomic dispersion Fe‐N x species on N co‐decorated hierarchical carbon layers, resulting in single‐atom OER/ORR the first time. The abundant atomically dispersed are catalytically active, structure offers more...
