ZnCo2O4 Quantum Dots Anchored on Nitrogen‐Doped Carbon Nanotubes as Reversible Oxygen Reduction/Evolution Electrocatalysts

ZnCo2 O4 quantum dots anchored on nitrogen-doped carbon nanotubes (N-CNT) retain the high catalytic activity of ZnCo2 O4 to oxidize water while enabling an efficient oxygen reduction performance thereby combining these desirable features. These advantages realize a bifunctional catalytic activity for ZnCo2 O4 /N-CNT that can be used in rechargeable zinc-air batteries.
