Ag nanoparticles were produced through the reduction of AgNO3 with NaBH4 in an aqueous solution using well-used stabilizer such as PVP , PVA , HTAB, SDS. Variable was contents of stabilizer, each kind of stabilizer. AgNO3 forms water-soluble chelate with NH4OH in a base solution. With the reduction of this chelate, using NaBH4, Ag nanoparticles are successfully produced. In the present work, the stabilizer takes effect the size of Ag nanoparticles. The silver nanoparticles are characterized on Transmission Electron Microscope (TEM), UV-Vis Spectra, Particle Size Analyzer (PSA). |
