- Abstract
- Visible-light responsive TiO₂:Zr, N powders were prepared by polymer complex solution methodand the particle properties were characterized by using transmission electron microscope, BET method, X-ray dif-fractometer and UV-Vis spectrophotometer. The photocatalytic reactivity of the catalysts was also estimated byanalyzing NO degradation. Polyhedral TiO₂ powder having about 20 nm in the average particle diameter was suc-cessfully prepared. The XRD analysis revealed that the as-prepared powder consisted of anatase and rutile phases.The light absorption of the as-prepared TiO₂:Zr, N powder was shifted to the visible light. In addition, the as-pre-2:Zr, N nanoparticles showed the higher photocatalytic activity than the commercial TiO₂ under both UVand visible lights.
