Bamboozled ! High‐aspect‐ratio TiO 2 nanowires (see image) that are vertically split off from anodic titanium oxide nanotubes are prepared by anodization of titanium foils. The bamboo‐splitting model based on the hydrolysis of a small amount of water in viscous ethylene glycol at high voltage is proposed as the mechanism of the formation of the TiO 2 nanowires.
