Arrays of ordered hollow urchin‐like ZnO single‐crystal nanowires with controlled core dimensions and wire morphology are obtained by a new method that combines electrochemical deposition with colloidal templating rendered electrically conductive. This method opens new opportunities for processing novel metal oxide or hydroxide materials based on a similar growth mechanism. Such ordered structures exhibit superior optical reflectance compared to nanowire arrays.
