This work reports the synthesis of nanostructured ZrO 2 by anodization of zirconium electrodes at potentials well below the range of 10–50 V used as a standard procedure. Zirconium was first anodized in a 1M (NH 4 ) 2 SO 4 electrolyte and then further anodized in the presence of fluoride ions added to the electrolyte as NH 4 F. The maximum potential applied to zirconium during the whole process was 1 V with respect to an Ag/AgCl (sat.) reference electrode. Amorphous films of ZrO 2 consisting of nanopores and nanowire‐like structures were produced with this low‐potential methodology.
