SONOCHEMICALLY ASSISTED SYNTHESIS OF ZNO NANOPARTICLES: A NOVEL DIRECT METHOD

Nanocrystalline ZnO particles were prepared by a novel sonochemical route from zinc acetate and sodium hydroxide without any requirement of calcination steps at high temperature and without surfactants. Variations in several parameters and their effects on the structural (crystal size and morphology) properties of nanoparticles were investigated. Characterizations were carried out by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), IR spectroscopy, Thermal Gravimetry Analysis and Diffrential Thermal Analysis (TGA/DTA).
