In article number 2002753, Lirong Zheng, Aijuan Han, Junfeng Liu and co‐workers report the development of a manganese single‐atomic‐site catalyst anchored on porous nitrogen‐doped carbon with Mn‐N 4 structure, which exhibits superior electrocatalytic activity and stability for the alkaline oxygen reduction reaction (ORR) and in zinc‐air batteries. Furthermore, operando XAFS is applied to uncover the mechanism under realistic conditions. This work paves the way to construct high‐performance ORR electrocatalysts through rational design.
