Preparation and Photocatalytic Property of Zinc Oxide Nanoparticle

Abstract:

ZnO nanorods were obtained by hydrothermal method using Zn (NO₃)₂ and N₄(CH₂)₆ as raw materials, crystalline nanoplate ZnO grew on the columnar facets of the primary ZnO rods when citrate was introduced in the reaction system. The crystalling phase of ZnO particle was characterized by X-ray diffraction, the morphology was observed by SEM, the structure was indicated by FTIR. The result showed that the average nanoparticle diameter of ZnO was around 60 nm. Through the photocatalytic degradation of dibutyl phthalate (DBP) in aqueous solution under the illumination of UV light, nanoplate ZnO displayed high photocatalytic activity, the degradation efficiency was rising to 87.8% at 60 min illumination time.
