Abstract

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-N4 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.
