Abstract

Visible-light responsive TiO_2:Zr, N powders were prepared by polymer complex solution method and the particle properties were characterized by using transmission electron microscope, BET method, X-ray diffractometer and UV-Vis spectrophotometer. The photocatalytic reactivity of the catalysts was also estimated by analyzing NO degradation. Polyhedral TiO_2 powder having about 20 um in the average particle diameter was successfully prepared, The XRD analysis revealed that the as-prepared powder consisted of anatase and rutile phases. The light absorption of the as-prepared TiO_2:Zr, N powder was shifted to the visible light. In addition, the as-prepared TiO_2:Zr, N nanoparticles showed the higher photocatalytic activity than the commercial TiO_2 under both UV and visible lights.
