Abstract
A novel photodegradable polyvinyl chloride (PVC)–vitamin C (VC)–TiO 2 nano-composite film was prepared by embedding VC modified nano-TiO 2 photocatalyst into the commercial PVC plastic. The solid-phase photocatalytic degradation behavior of PVC–VC–TiO 2 nano-composite film under UV light irradiation was investigated and compared with those of the PVC–TiO 2 film and the pure PVC film, with the aid of UV–Vis spectroscopy, scanning electron microscopy (SEM), weight loss monitoring, and X-ray diffraction spectra (XRD). The results show that PVC–VC–TiO 2 nano-composite film has a high photocatalytic activity; the photocatalytic degradation rate of it is two times higher than that of PVC–TiO 2 film and fifteen times higher than that of pure PVC film. The optimal mass ratio of VC to TiO 2 is found to be 0.5. The mechanism of enhancing photocatalytic activity is attributed to the formation of a Ti IV–VC charge-transfer complex with five-member chelate ring structure and a rapid photogenerated charge separation is thus achieved.
