Graphical Abstract

Electrocatalytic Oxygen Reduction

In article number 2207991, Cheng-Yan Xu and co-workers develop a self-sacrificing strategy to encapsulate single-atom Fe-N4O1 species into carbon hollow spheres assembled by ultrathin nanosheets Fe1–N–C hollow microspheres (Fe1/N-HCMs). Such highly open architecture is supposed to be an ideal platform to isolate and fully expose single metal atoms. Benifiting from the highly open architecture and abundant Fe-N4O1 active sites, the Fe1/N-HCMs exhibit excellent oxygen reduction performance.
