Preparation of TiO₂ and TiO₂-CdS Photocatalayst Using the Supercritical Fluid Method

ABSTRACT

TiO$_2$ and TiO$_2$-CdS which were expected to be highly activated photocatalysts with semiconductor properties, were prepared using supercritical fluid method. The powders prepared by supercritical fluid were agglomerate foam in 2-3 ${mu}{textrm}{m}$ size and the primary particles of 20 nm were arranged in the powders. The powders which were prepared by supercritical fluid method were anatase phase without any heat treatment.

Key words: Supercritical fluid method, $TiO_2$, $TiO_2$-CdS photocatalyst
