Synthesis and study silver nanoparticles by chemical method

In this paper, Ag nanoparticles with various sizes and forms are made by using reduction methods of Ag ions in aqueous solutions in the presence of strong reducing agents like hydrogen peroxide (NaBH4) with different concentrations of silver nitrate AgNO3 (1mM to 0.9mM) improving its effect on the stability of the nanoparticles.From the results, stability of the Ag nanoparticles is due to the ions of NaBH4 that surrounding the nanoparticles and decreased from aggregating as demonstrated by using UV-VIS spectra, Particle size analyzer (PSA) , Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) to determine their behavior as catalyst materials and analysis the kinetics of reactions.
