The aim of this study is to investigate the morphology and surface species of ZrO 2 film formed in a fluorinated ethylene glycol electrolyte by anodization process. In this work, no water was added into the NH 4 F/ethylene glycol electrolyte. Possible formation mechanism of anodic ZrO 2 nanostructures in the NH 4 F/EG electrolyte was also explored. As a result, the porous ZrO 2 film with the thickness of 1.5 – 2.5 µm was produced. From the top view, it is observed that the surface consists of rings with diameters of 100 – 160 nm. However, the oxide does not consist of any tubular structure. The FTIR spectrum of the film shows that the top of anodic ZrO 2 film is covered by anion contamination, e.g. OH − and CO 3 − .
