Abstract

Oxygen Reduction Reaction In article number 2305062, Tianyu Xia, Han Gao, Haizhong Guo, and co-workers develop the quasi-octahedral core-shell electrocatalyst with L10-PtCo as the core and ultrathin, strained PtIr layer as the shell. It delivers impressive activity and durability in the oxygen reduction reaction (ORR). In the dual catalysis of ORR and oxygen evolution reaction, a small overpotential difference is observed.
