Electrochemical deposition of zinc nanorods into the anodic aluminium‐oxide template from ionic‐liquid electrolyte is reported. For the first time, the electrodeposition from an ionic liquid is performed in a porous alumina template, anodically grown on the aluminium substrate without complete removal of the barrier layer. The two‐step process was applied; first, with alternating‐current pulse nucleation of zinc nanoparticles on the bottom of the pores, followed by direct‐current growth of the rods. The electrolyte consisted of 0.5 M ZnCl 2 in choline chloride and ethylene glycol in a 1:2 molar ratiod. The resulting zinc nanorods are approximately 3 μm in length and 70 nm in diameter. The achieved fill factor of the pores is in the 70–80 % range.
