Abstract: Composite precursor was synthesized by mixing ZnO nanorod which was attained by hydrothermal method and polyvinyl chloride solution, ZnO nanorod/PVC composite was prepared by calcinating the precursor at appropriate temperature. Also, the composite was characterized by XRD, TEM, SEM, IR, UV-Vis and ESR. We studied on the photocatalytic property of ZnO nanorod and its composite under visible light, and evaluated the effect of preparations using methyl orange(MO) as a probe reaction. The experiments showed the optimum conditions for preparing this composite are: the mass ratio of ZnO nanorod and PVC is 1∶1, calcined temperature is 250 ℃ and calcined time is 1 h. Otherwise, the composite can degrade MO up to 88% under illumination with 15 W home light for 3 h when the concentration of MO is 10 mg/L, and the dose of photocatalyst is 0.5 g/L. The results above indicated that ZnO nanorod/PVC composite has good photocatalytic property under visible light.
