A new type of ZnO/conjugated polymer(P) complex particles was successfully designed and prepared from the precursors PVC and ZnCl₂,and used as a catalyst to decolorize dye methylene blue(MB).Under natural light and at room temperature,the catalytic activity of ZnO was dramatically enhanced by the modification with this P,and MB could be fully decolorized within 5 min.When m(ZnCl₂):m(PVC) was about 3:1,the ZnO/P complex catalyst could be reused for 6 times with a high activity.The complex catalyst was also characterized by IR and UV-Vis techniques,and the results show that P was a conjugated polymer with active groups and linked to ZnO by Zn-O-C bond.The doping of P greatly extends the photo response region of ZnO.
