Abstract
This study focuses on the difference of photocatalytic activity depending on crystal structure type of nanoparticles ($TiO_2$) and nanotubes (TNT). The photodecomposition of 2-chlorophenol on the synthesized $TiO_2$, Sn-impregnated $TiO_2$, TNT, and Snimpregnated TNT were evaluated. The characteristics of the synthesized photocatalyts, TNT, Sn/TNT, $TiO_2$, and Sn/$TiO_2$ were analyzed by X-ray diffraction (XRD), transmission electron microscopy (TEM), and UV-Visible spectroscopy (UV-Vis), and cyclic voltammeter (CV). The water-suspended 2-chlorophenol photodegradation over $TiO_2$ (anatase structure) catalyst was better than that over pure TNT. Particularly, the water-suspended 2-chlorophenol of 10 ppm was perfectly decomposed within 4 h over Sn/$TiO_2$ photocatalyst.
