Abstract

A highly active and stable Fe₃C-containing Fe/N/C catalyst, derived from a cationic Cd(II)-based metal–organic framework involving accurate control over Fe-doping via anion-exchange with potassium ferricyanide, shows superior oxygen reduction performance over the benchmark Pt/C catalyst in an alkaline electrolyte.
