Immobilization of TiO_2 nanoparticles on activated carbon fiber and its photodegradation performance for organic pollutants

查看参考文献37篇

文摘 The immobilization of titanium dioxide (TiO_2) on activated carbon fiber (ACF), (TiO_2/ACF), was accomplished by sol-gel-adsorption method followed by calcination at temperatures varying from 300 to 600 ℃ 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 TiO_2/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 TiO_2/ACF photocatalyst and the sample calcined at 500℃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, TiO_2 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.
