A Simple Method for Preparation of Nano-sized ZnO

ثبت نشده
چکیده

Nano is an advanced technology which in recent years has had numerous applications in different fields such as industry, biotechnology, energy, environment and etc. In this paper, ZnO nanoparticles were synthesized by simple method of precipitation sounds more plausible. ZnSO4 and NH4OH were used as precursors to yield ZnO powders. The synthesized ZnO nanoparticles were characterized by X-ray diffraction measurements (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX). According to the results of XRD analysis, the purity of ZnO nanoparticles was obtained; based on the William-Hal method, the mean size of particles was achieved equal to 30 nm. This test has also shown the high crystallinity of the ZnO nanoparticles. As SEM analysis revealed, the morphology of ZnO nanoparticles to be flake like shapes with the mean particle size of 30 nm. Finally, the analysis of the synthesized nano sample by using percentage of EDX has indicated that the purity of ZnO was quite high.
