Using nitrogen-rich polymeric network and iron(II) acetate as precursors to synthesize highly efficient electrocatalyst for oxygen reduction reaction in alkaline media

We report a novel Fe-N/C catalyst using a nitrogen-rich polymeric network and iron(II) acetate as the precursors. Compared to commercial Pt/C catalyst, the prepared Fe-N/C catalyst exhibits superior ORR activity in alkaline electrolytes, and comparable ORR activity in acidic media. The results obtained are significant for the development of new Fe-N/C catalysts for fuel cells.210
