The hole story : Highly ordered anodic porous alumina with a hole interval of 13 nm was fabricated (see SEM image). The ordered structure of a 2D array of monodisperse γ‐Fe 2 O 3 nanoparticles was transferred to Al through the deposition of Al by sputtering. The formed shallow concaves on the Al surface could act as initiation sites for hole development and guided the growth of the holes during anodization.
