Abstract：
 A metallic wire screen skeleton material-carried nm-clas cystol TiO2 photocatalyst is prepared through preparing transistion layer sol from n-butyl titanate as precursor, preparing active layer sol from n-butyl titanium or TiCl4 and pore-forming agent, coating the transition layer sol on the cleaned metallic wire screen skeleton-shaped carrier, directly coating the active layer sol, drying and calcining; or preparing nm TiO2 powder suspension, and attaching it the said carrier to form the photocatalyst. Its advantages include high adhesion, low gas resistance and high photocatalytic efficiency and activity.
