Ni x Co 3− x O 4 nanowire arrays are grown on a Ti foil for efficient oxygen evolution reactions. Ni‐doped nanowire arrays have higher electrocatalytic activity than pure Co 3 O 4 . The success of the nanowire electrodes results from their high surface areas and direct electron contact to the conductive substrate.
