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/Fe 3 C‐functionalized surface of the framework dramatically enhance the ORR activity.
