Effect of Temperature towards the Corrosion Behavior of Titania Nanotube Anodized in H2O2-Based Organic Electrolyte
Hydrogen peroxide (H2O2) is a stronger oxidizing agent relative to the commonly used H2O in anodization of Titania Nanotube (TNT). Despite having higher oxide growth rate and more superior photocatalytic property, the substitution of H2O2 as oxygen source is sometimes accompanied with foil corrosion. In this work, it is shown that foil corrosion is originated from temperature elevation during anodization process. Conversely, foil corrosion can be prevented by monitoring the anodization temperature. Essentially, the corrosion of foil is not directly influenced by the type of oxidation source used. Foil corrosion occurs due to temperature elevation when using H2O2 as oxidation source.
