Abstract

Abstract Single‐atom FeN 4 sites at the edges of carbon substrates are considered more active for oxygen electrocatalysis than those in plane; however, the conventional high‐temperature pyrolysis process does not allow for precisely engineering the location of the active site down to atomic level.
