Photocatalayst and Decomposition Properties of TiO2 and TiO2-CdS Powders Prepared by Supercritical Fluid Method
TiO$_2$ and TiO$_2$-CdS powders which were expected to be highly activated photocatalysts were prepared using supercritical fluid method (SCF). The prepared photocatalyst TiO$_2$ powders were crystalline of anatase and ultrafine spherical powders with large specific surface area. When photodecompositoion reaction was done with TiO$_2$ powders prepared by SCF as a photocatalyst in DCA (Dichloroactic Acid) solution, a hazardous organic compound, the photocatlyst, properties of TiO$_2$ powders prepared by SCF were better than that of commercial TiO$_2$ powders.
Key words: Superclitical fluid method, $TiO_2$, $TiO_2$-CdS photocatalst, Decomposition property
