Visible Photocatalytic Degradation of Polyvinyl Chloride Film by AgNbO3 Photocatalyst
摘要
Abstract
Pure polyvinyl chloride ( PVC ) film and PVC-AgNbO3 hybrid films were prepared on glass sub-strates via a coating method. The photocatalytic degradation experiments were carried out under xenon lamp irradiation. The samples were characterized by X-ray diffractometer ( XRD ) , scanning electron microscope ( SEM) , and Fourier transform infrared spectrometer( FTIR) . The results show that PVC-AgNbO3 hybrid films have much higher photocatalytic degradation activity than pure PVC film. The photodegradation performance of the films can be evaluated directly by their mass loss. The mass loss of the pure PVC film was about 4. 09%after irradiation under xenon lamp for 120 min, that of the PVC-3% AgNbO3 , PVC-6% AgNbO3 , PVC-9%AgNbO3 , and PVC-15% AgNbO3 films reached about 20. 36%, 23. 52%, 27. 62% and 33. 83% after irra-diation for 120 min, respectively. The mass loss of PVC increased with the increase of the content of AgNbO3 . This result prove that the presence of AgNbO3 remarkably promote the photocatalytic degradation rate of PVC film.关键词
