The iron nitride nanoparticles embedded in N doped carbon catalyst material has been successfully synthesized and employed as a promising alternative for oxygen reduction reaction (ORR). The resultant catalyst exhibits superior electrocatalytic activity, good stability and low cost. Here, we pay more attention to "high dispersion" of iron, nitrogen and carbon. We developed a uniform dispersed Fe N C catalyst synthesized by one-pot method, which exhibits superior electrocatalytic activity for ORR in alkaline media. Moreover, we also studied the influence of various pyrolysis temperatures and different mass ratio of nitrogen precursors and iron source on ORR electrocatalytic activity.
