Associating Co single atoms with RuO2 nanoparticles anchor on nitrogen-doped ultrathin porous carbon nanosheets as effective bifunctional oxygen electrocatalysts for rechargeable Zn–air batteries

The picture shows Co single atom-decorated RuO 2 nanoparticles anchored on nitrogen-doped ultrathin carbon nanosheet (Co SA -RuO 2 -NUCN). The bifunctional catalytic process (ORR/OER) of Co SA -RuO 2 -NUCN is also fully presented.
