Oxygen reduction reaction (ORR) is Achilles' heel of zinc-air battery. The ideal electrocatalyst for ORR should combine both high activity and high stability. In order to achieve this goal, a new N, S co-doped carbon coated Fe 3 N nanoparticles electrocatalyst with redistributed charge was designed and synthesized. The doping of S elements destroyed the ordered structure of carbon matrix, which cooperated with Fe 3 N nanoparticles to cause charge redistribution of carbon atoms.Furthermore, the carbon shell protected Fe 3 N from corrosion during the electrocatalytic process. Fe 3 N/NSC electrocatalyst showed excellent ORR property with E 1/2 = 0.86 V, and the zincair battery assembled based on it could run stably for more than 650 hours. This work provides a strategy to regulate the redistributed charge of carbon atoms to boost its electrocatalytic activity and stability together.
