Production of Anodic TiO2 Nanofilms and their Characterization

This research study presents an exploration of the oxide properties that can be obtained by anodising commercial purity titanium in diluted sulphuric acid and phosphoric acid solutions. Correlations between oxide growth rate and electrolyte composition and concentration, as well as a quantification of oxygen evolution occurring at the electrode surface as concurrent anodic reaction, are presented. Much effort was dedicated to identifying a suitable technique for thickness measurements on oxides thinner than 50 nm.
