Title: Enhancement of the photocatalytic property of TiO{sub 2} columnar nanostructured films by changing deposition angle

Abstract

Highlights: • Isolated and inclined columnar TiO{sub 2} nanostructures were obtained by sputtering Ti, and subsequently annealing. • The film performed photocatalytic decolorization effectively under UV irradiation. • The photocatalytic efficiency increased with deposition angle, which results in a more porous micro structure of the films. - Abstract: Isolated and inclined columnar nanostructured TiO{sub 2} films were obtained by sputtering titanium with glancing angle deposition method and subsequently annealing in air. Compared with flat film, TiO{sub 2} film fabricated with this method has higher porosity; compared with TiO{sub 2} powder, it overcomes the obstacles of immobilization and recycling. The TiO{sub 2} photocatalysis was evaluated by the degradation of methyl orange under UV light. It was indicated that the photocatalytic performance increased with deposition angle, which changed the porosity of the films. The relationship between deposition angle (the angle between the target and substrate surface) and the TiO{sub 2} columnar inclination angle (the angle between TiO{sub 2} columnar and substrate normal) was discussed.
