Sonochemical Synthesis of Metal Nanoparticles

Abstract

In this chapter, sonochemical synthesis of nanometer sized metal particles is described and consists of sonochemical reduction of the corresponding metal ions in aqueous solutions. The reduction mechanism is suggested to be due to the reactions with reducing species formed from the sonolysis of organic additives and water. The rate of reduction of metal ions can be changed by changing the types and concentration of organic additives. In addition, various parameters such as ultrasound intensity, ultrasound frequency, dissolved gas, position of reaction vessel, etc. also affect the rate of reduction of metal ions. It is important to control the rate of reduction of metal ions, because the size..
