Surface treatment of Porous Titania Thin Films fabricated by Spray Deposition to enhance the photoactivity |
| 초록 |
TiO2 film has very effective photo degradation activity for organic contaminants in water and air under UV irradiation due to its high photosensitivity, non-toxic nature, large band gap and stability. However, film-typed photocatalysts normally show lower photocatalytic activity than powdered ones due to its relative low surface area. Therefore, porous TiO2 films with various sizes were generated by spray deposition to increase surface area. Also, the influence of oxygen plasma treatment and acid treatment of porous TiO2 films was investigated for better photocatalytic activity. The photoactivity of each film was characterized by UV-vis spectrometer. X-ray Photoelectron Spectra (XPS) revealed that the ratio of titanium dioxide to titanium suboxide. The morphology and thickness of films were characterized by scanning electron microscopy (SEM). |
