| 제목 | TiO 2 –based nanostructured photocatalysts for high photocatalytic degradation of organic dyes |
| 초록 | Nanostructured TiO 2 would have large surface area with high pore volumes, which is adequate for adsorbing plenty amount of organic dyes (or pollutants) in water and air. Also, TiO 2 is well-known as a highly reactive photocatalyst under UV light irradiation. For faster photocatalysis process, TiO 2 should be improved its light-harvesting ability, and charge transfer ability to generate reactive oxygen species. Here, other metal oxide (WO x and FeO x )–incorporated mesoporous TiO 2 were prepared via hard-template method using (1) titanium glycolate spheres and (2) KIT-6 (Ia3d mesostructure). (1) WO x -incorporated mesoporous TiO 2 showed faster photocatalytic degradation rate than mesoporous TiO 2 exhibited. This phenomenon would be explained its larger surface area, and higher crystallinity of anatase phase. (2) Ordered mesoporous Fe 2 O 3 -TiO 2 nanocomposites decomposed organic dyes effectively under both UV and visible lights. The heterojunctions between Fe 2 O 3 and TiO 2 nanoparticles would help excitons easily separated into the conduction and valence band, thus, reactive oxygen species could be generated without difficulty. |
