Abstract

A nitrogen doped nano-ZnO/PVC composite was prepared. The composite exhibits strong absorption in the ultraviolet and visible light regions according to measurement results by FT-IR and UV-visible diffuse reflectance spectroscopy. The effect of the composite on the photocatalytic degradation of methyl orange was examined. The results show that the existence of PVC in the composite can reduce the annihilation probability of electrons with cavities within ZnO, thereby broaden the spectral response range and correspondingly enhance the photocatalytic efficiency of the composite in visible light.

Key words: composites ZnO photocatalyst PVC
