A micro‐/nanostructured “superaerophilic” electrode constructed by direct growth of cobalt‐incorporated and nitrogen‐doped carbon‐nanotube arrays with subsequent hydrophobic modification is demonstrated for a high‐performance oxygen‐reduction‐reaction electrode, superior to the Pt/C–air electrode. This high performance is attributed to the simultaneously accelerated gas‐diffusion and electron‐transport processes induced by the unique structural advantages.
