Fe–P: A New Class of Electroactive Catalyst for Oxygen Reduction Reaction

It has been long thought that Fe-N-C structure, where Fe is bonded with an electronegative heteroatom N, plays a key role as nonprecious metal catalyst for oxygen reduction reaction (ORR) in fuel cells. However, electrocatalytic activity of Fe bonded with electropositive heteroatom P has never been considered for ORR. Herein we report the electrocatalytic activity for ORR of new Fe-P-C.
