Abstract ZrO{sub 2} nanotube arrays were formed by anodizing zirconium sheet in ethylene glycol (EG) and EG added to it KOH (EG/KOH) electrolytes. The effect of KOH addition into EG electrolyte to the morphology of nanotubes and their crystallinity was investigated. It was observed that the tubes with diameter of ∼80 nm were formed in EG electrolyte with <0.1 vol % water, but the wall smoothness is rather poor. When KOH was added into EG, the wall smoothness of the nanotubes improve, but the diameter of tubes is smaller (∼40 nm). Despite smoother wall and small tube diameter, the degradation of methyl orange (MO) on the tubes made in EG/KOH is less compared to the tubes made in EG only. This could be due to the less tetragonal ZrO{sub 2} presence in the tubes made in EG/KOH.
