Abstract

In this paper, nickel oxide thin films on the titanium substrate were prepared by the sol-gel dipcoating technique with the precursors NiS04.7H2O and acetic acid. The obtained thin films have a good adhesion to the substrate. The electrochemical behaviors of the NiOxHy thin films were investigated in KOH 1 M solution by the voltammetry technique. The effect of addition ofplatinum, heating temperature and the dip coating number on the electrochemical behavior was also investigated. The thin films have high electrochemical properties at 270oC and at third dip coating.
