Abstract

In this study, the basic understanding of precipitation method to synthesis of Zinc Oxide nanopowders has been demonstrated. The synthesised nanopowders were formed by mixing           Zn (O₂CCH₃)₂ (H₂O)₂, diethylene glycol (DEG) and deionized water, then the mixed solution was heated at two different temperatures 140 ⁰C and 180 ⁰C for 2 hours. The synthesised nanopowders have been studied by different characterisation techniques as X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Dynamic Light Scattering (DLS), and Energy-Dispersive X-ray spectroscopy (EDX). Results demonstrated that the pure Zinc oxide nanopowders with low trace elements, with uniform morphology, controllable size and narrow-size distribution in diameter were achieved. The synthesized nanopowders can be used as       active filler for rubber and plastic, catalyst and gas sensor.
