A Highly Efficient Electrocatalyst for the Oxygen Reduction Reaction: N‐Doped Ketjenblack Incorporated into Fe/Fe₃C‐Functionalized Melamine Foam

Abstract

Inspired by the tetrapod structures of a breakwater, a highly efficient electrocatalyst for oxygen reduction reaction (ORR) in alkaline solution has been created from low-cost, commercial melamine foam and ketjenblack. The unique porous architecture greatly facilitates rapid mass transport, while the N-doped ketjenblack and Fe/Fe3C-functionalized surface of the framework dramatically enhance the ORR activity.
