The title nanotubes were synthesized by template‐assisted one‐step electrodeposition and found to exhibit markedly enhanced electrocatalytic activity toward oxygen reduction, which can be attributed to a combination of several favorable factors: the multicomponent nature with which different elements work synergistically, the strain and electronic effects associated with surface dealloying, and their hollow and porous geometry.
