Ultrasound assisted additive free synthesis of nanocrystalline zinc oxide

A novel method for the synthesis of nanocrystalline zinc oxide without any additive was developed using zinc acetate and 1,4-butanediol through sonication. The structure and morphology of prepared nanocrystalline zinc oxide was investigated by various techniques like TEM. XRD, EDAX, UV-Vis spectroscopy. The solvent 1,4-butanediol played a dual role of fuel as well as capping agent eliminating addition of any extraneous species. The results showed that using ultrasound sonication is green, cost effective compared to conventional wet chemical method for ZnO nanoparticle synthesis. (C) 2010 Elsevier B.V. All rights reserved.
