Abstract High‐active nonplatinum group metal oxygen reduction reaction (ORR) catalysts have great potential to improve fuel cell and metal–air battery performance due their efficiency cost‐effectiveness. However, a fundamental understanding of size‐dependent structure–performance relationships remain elusive. Here mesoporous‐dominant carbon nanoreactor with dimensions in the range 15–43 nm edge‐rich defective atomic Zn sites is designed. The crystal size pore diameter this nanoreactors can be precisely adjusted enable tunable mass diffusion pathways porosities. Importantly, hydrophobic nature 25 maximizes nonkinetic advantages active site exposure rapid O 2 transfer at triple‐phase interface. developed Zn‐N‐P/NPC delivers outstanding alkaline acidic ORR half‐wave potentials 0.92 0.80 V, respectively, as well excellent zinc–air charge/discharge over 400 h under 20 mA cm −2 . X‐ray absorption spectroscopy theoretical calculations indicate that enhanced catalytic activity stems from introduction P atoms edge defects effectively exciting localized electronic asymmetric distribution species. findings provide new perspectives on effect porous supports for development efficient cathodes multifunctionality.
