METHOD OF MANUFACTURING NANO SILVER WITH CONTROLLED SIZE AND SHAPE

摘要

Fabrication of nanomaterials have gained importance due to the novelty in the properties of nanoparticles. Many recent research efforts have been focussed on the development of an economical and simpler method of synthesis of nano particles for both industrial, medical and other applications. Here we are concerned with the synthesis of silver nanopowder from its salt employing reduction process. Sodium Citrate ion finds a role as a reductant while the process temperature ranges between 293K-368K. It is supposed that the complexing of silver with the citrate ions and the process parameters dictate the size of the nanoparticles to be formed. The prepared NanoSilver particles have been dried by freeze drying process to avoid the property change at high temperature during the drying process. These materials might serve as ideal materials as catalysts, adsorbents, antibiotics etc.. These materials will have profound technological applications in the field of electronics, biotechnology, energy environment etc.
