Synthesis of N Doped Titania Photocatalyst by Using an Electrochemical Oxidation of TiN Layer

Abstract:

In order to improve the photocatalytic efficiency, the N doped anodic titania film for photocatalyst was synthesized by anodic oxidation of TiN layer in sulfuric electrolyte, and the photocatalytic properties of N doped TiO₂ layer were investigated. During the oxidation process of the TiN layer, nitrogen was doped into the anodic titania film due to the change of the titanium nitride layer to TiO₂ layer film. In the evaluation of dye degradation, N doped titania catalyst shows much higher efficiency than non-doped titania film.
