ZnO nanostructures of different methods and sizes were grown in a controlled manner using a simple hydrothermal and sonochemical technique. Controlling the content of concentration and temperature of the reaction mixture, spherical nanoparticles ZnO structures could be synthesized at temperatures 100-150 °C with excellent reproducibility in solvothermal and at different power and time in sonoch...

A novel sonochemical approach was developed for the synthesis of different core/shell structures of Fe3O4/SiO2/Ag nanocubes and SiO2/Ag nanospheres. The total reaction time of the three sonochemical steps for the synthesis of Fe3O4/SiO2/Ag nanocubes is shorter than that of the previously reported methods. A proposed reaction mechanism for the sonochemical functionalization of the silica and the...

Cyanide is a species of high toxicity that found mostly in industrial effluents such as electroplating, metal mining, metallurgy and metal cleaning processes. Entrance of it to existence environment contains very health hazardous. Objective of this study was the determination of efficiency of sonochemical technology for cyanide removal from aqueous solutions. In this study, it has been used fro...

The efficacy of sonochemical reactors in chemical processing applications has been well established in the laboratory scale of operation though at a given set of operating parameters and no efforts have been directed in terms of maximizing the free radical production. In the present work, the effect of different operating parameters viz. pH, power dissipation into the system, effect of additive...

This study aims to analyse the use of biowaste-derived carbon in enhancing photocatalytic effect Earth-abundant visible light active goethite (??FeOOH). The biowaste material used this case is seeds Indian blackberry fruit. FeOOH/C composite has been synthesized using an assisted sonochemical technique. photocatalysts have characterized powder x-ray diffraction, nitrogen adsorption isotherms an...
