Atomically dispersed metal-nitrogen-carbon (M-N-C) catalysts are regarded as ideal catalytic materials for the oxygen reduction reaction (ORR) under alkaline conditions. Compared with other ORR catalysts, M-N-C catalysts exhibit notable advantages, including low cost, high atomic utilization efficiency, and considerable catalytic potential. We provide a systematic review of recent research advances in enhancing the ORR performance of M-N-C catalysts, focusing on catalytic activity and stability. First, the reaction mechanism of the ORR on the surfaces of the M-N-C catalysts is elucidated. Second, the primary strategies employed in recent years to improve their catalytic activity and stability are summarized. Finally, critical research directions that should be prioritized to expedite the commercialization of M-N-C catalysts are outlined.
