Degradation mechanism and kinetic model for photocatalytic oxidation of PVC–ZnO composite film in presence of a sensitizing dye and UV radiation

Effects of ZnO quantum dots on the photostability of acrylate photopolymers used as recording materials

“…In the case of poly(vinyl chloride) (PVC), ZnO could photocatalyse the degradation in aqueous medium under oxygen of air and light [26,27]. In the presence of oxygen or water, the photogenerated hole-electron pairs could yield hydroxyl radicals HO • .…”

Preparation, characterization and photocatalytic activity of Co-doped ZnO powders

“…As a suitable alternative photocatalyst to TiO 2 , ZnO has a similar band gap energy (3.2 eV) to TiO 2 [3], larger quantum efficiency and higher photocatalytic efficiencies than TiO 2 [4,5]. It has also suggested that ZnO costs lower than TiO 2 for decolorization of organics in aqueous solutions [6].…”

Photocatalytic activity of nanostructured ZnO films prepared by two different methods for the photoinitiated decolorization of malachite green

“…To solve this problem, various non-ionic and polymer-type surfactants such as polyethylene glycol (PEG) [31] and polyvinyl alcohol (PVA) [32] have been widely applied in the sol-gel process. To the best of our knowledge, the studies concerning preparation of photocatalyti- cally active ZnO-polymer nanocomposite films are very scarce [33]. Chakrabarti et al have investigated the degradation of polyvinyl chloride films in aqueous medium using (PVC)-ZnO composite films [33].…”
