Abstract

Herein, we report an atomically dispersed Fe–N–C catalyst with axial oxygen ligands (FeN₄O/NC) synthesized for the first time by ultrafast Joule heating. The formation of oxygen species between FeN₄ and graphene offers high activity and stability for the ORR. The calculations indicate that FeN₄O/NC offers an optimal adsorption–desorption of oxygen-containing intermediates, providing a promising approach to designing efficient single-atom electrocatalysts.
