Structural, Optical and Photocatalytic Properties of ZnO Nanoparticles Prepared by Precipitation Method

Abstract:

ZnO nanoparticles were synthesized from PEG600 diacid modified-Zn (CH₃COO)₂.2H₂O solution by precipitation method and an aqueous NaOH solution was used as precipitating agent. The crystal structure, morphology and optical property of ZnO nanoparticles were characterized by XRD, SEM and UV-Vis spectrophotometer, respectively. The crystallinity increased while the E_g value decreased as a function of PEG600 diacid concentrations. The ZnO nanoparticles that had the highest crystallinity and lowest E_g value exhibited the highest efficiency of photocatalytic degradation of about 90% when irradiating with a UV light for 3 h.
