摘要	The immobilization of titanium dioxide (TiO2) on activated carbon fiber (ACF), (TiO2/ACF), was accomplished by sol gel-adsorption method followed by calcination at temperatures varying from 300 to 600 degrees C in an argon atmosphere. The material properties were determined by scanning electron microscope (SEM), X-ray diffraction (XRD) and nitrogen adsorption. The photodegradation behavior of TiO2/ACF was investigated in aqueous solutions using phenol and methyl orange (MO) as target pollutants. The effects of calcination temperature, photocatalyst dosage, initial solution pH and radiation time on the degradation of organic pollutants were studied. It was found that organic pollutants could be removed rapidly from water by the TiO2/ACF photocatalyst and the sample calcined at 500 degrees C exhibited the highest removal efficiency. Kinetics analysis showed that the photocatalytic degradation reaction can be described by a first-order rate equation. In addition, the possibility of cyclic usage of the photocatalyst was also confirmed. Moreover. TiO2 is tightly bound to ACF and can be easily handled and recovered from water. It can therefore be potentially applied for the treatment of water contaminated by organic pollutants.
