Sonochemically Assisted Synthesis of ZnO Nanoparticles: A Novel Direct Method
Authors
Abstract:
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).

In the present work, the synthesis of Barium hexaferrite (BaFe12O19) nanoparticles in thepresence of a large excess amount of OH− anions by the hydrothermal method in the presence and absence of surfactants such as Sodium dodecyl benzene sulfonate and Triton X-114 was reported. The optimized temperature in the absence of surfactant was determined (200 °C) and then Barium hexaferrite nanoparticl...
