Facile Synthesis of ZnO Nanoparticles Using Mechanochemical Route and their Structural, Morphological and Thermal Properties

Abstract:

In the present work, we have prepared ZnO nanoparticles by a two-step mechanochemical synthesis method. The reaction was carried out in a paste state at room temperature with a short grinding time of 20 min. The prepared ZnO nanoparticles were characterized by using x-ray diffraction (XRD), transmission electron microscopy (TEM), fourier transform infrared spectroscopy (FT-IR), and thermogravimetric analysis-differential thermal analysis (TGA/DTA). XRD and TEM results demonstrated that ZnO have a single phase nature with wurtzite structure with high crystallinity. The lattice parameters calculated from XRD pattern are a= 3.25 Å and c= 5.248 Å and the average grain size of the ZnO nanoparticles was found to be ~ 20 nm (TEM) or ~22 nm (XRD). FTIR spectra demonstrated the peak at ~455 cm^-1 which correspond to stretching mode of ZnO.
