Fe single atoms and N co‐doped carbon nanomaterials (Fe‐N‐C) are the most promising oxygen reduction reaction (ORR) catalysts to replace platinum group metals. However, high‐activity Fe single‐atom catalysts suffer from poor stability owing to the low graphitization degree. Here, an effective phase‐transition strategy is reported to enhance the stability of Fe‐N‐C catalysts by inducing increased degree...
The oxygen reduction reaction (ORR) plays an important role in the fields of energy storage and conversion technologies, including metal–air batteries and fuel cells. The development of nonprecious metal electrocatalysts with both high ORR activity and durability to replace the currently used costly Pt‐based catalyst is critical and still a major challenge. Herein, a facile and scalable method is...
