Other AbstractA novel three-dimensional photocatalyst,TiO2 particulate film immobilized on activated carbon fibers (TiO2/ACFs),was prepared by liquid phase deposition. The photocatalyst was characterized by SEM,XRD,BET surface area and photodegradation of methylene blue solution. TiO2 particulate film,with a thickness of nearly 200 nm and grain sizes of 30~50 nm,was deposited on almost each carbon fiber. The inner space between adjacent fibers remained as unmodified ACFs,therefore,both UV illumination and polluted solutions were allowed to pass through the felt-form photocatalyst to form a three-dimensional environment for photocatalytic reactions. With BET surface areas of 400~600 m2/g,the TiO2/ACFs exhibited an enhanced adsorption of pollutants for photocatalysis. Comparative degradations indicated that photocatalytic activity of the TiO2/ACFs was slightly higher than that of Degussa P-25 TiO2. Two special properties,the three-dimensional structure and combined effects of ACFs’ adsorption and titania’s photodegradation,made contribution to high photocatalytic activity. Additionally,the TiO2/ACFs exhibited high stability and potentially application for practical usage.
