dc.description.abstractIn this study, the influence of calcination temperature on the morphology, chemical composition, and structure of ZnO nanoparticles (ZnO–NP) was investigated. The ZnO nanoparticles were synthesized by a co–precipitation method. Zinc acetate dihydrate was used for the synthesis of zinc oxide nanoparticles. Thermogravimetric analysis (TGA) of the precursor was performed to determine the calcination temperature. The results of the TG analysis indicate high stability of ZnO at temperatures above 325°C. Therefore the prepared samples were calcined at temperatures of 400°C, 500°C, 600°C, or 700°C. The ZnO nanoparticles were morphologically and structurally characterized by X–ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersion spectroscopy (EDS). The results of the XRD analysis show that pure ZnO is obtained by the co–precipitation method and that the ZnO nanoparticles have a wurtzite structure. The average crystallite sizes of the materials calcined at 400°C, 500°C, 600°C and 700°C were 32.07 nm, 32.89 nm, 35.63 nm and 38.48 nm, respectively. As the calcination temperature increases, the crystallite size also increases. The results of SEM analysis show that the nano–sized particles were obtained by the co–precipitation method and that the calcination temperature significantly affects the size and morphology of the particles. The results of the EDS analysis show that pure ZnO was synthesized, which is consistent with the results of the XRD analysis.
