Abstract
structure. The atomically dispersed metal species, though relatively low-loading grafted on AC (typical loading of 0.16 to 0.29 at%), are mostly distributed on the electrochemically accessible surface, resulting in improved metal utilization. The FeNC@AC-3 sample exhibited highly comparable catalytic performance to 20 wt% Pt/C for the alkaline oxygen reduction reaction, and superior Al-air battery performance. Our work may inspire the synthesis of other types of SACs for broad electrocatalysis applications at kilogram or even ton scale.
