Sandwich‐like, graphene‐based carbon nitride nanosheets (G–CN), among many other advantages, show an enhanced electrical conductivity. Oxygen atoms can thus access the catalyst surface easily and the rapid diffusion of electrons in the electrode during the oxygen reduction process is facilitated. G–CN nanosheets can hence serve as metal‐free electrocatalysts for oxygen reduction reactions (ORR) with excellent performance.
