Abstract

With the increased use of silver nanoparticles in modern day applications, kinetic information on the mechanism of their formation is useful for further studies on its reactivity in a biological environment. Silver nanoparticles were synthesized using a modified Turkevich method. The synthesized nanoparticles were characterized using UV-Visible spectroscopy. The data obtained were plotted as a function of time, and rate constants for the nucleation (k₁) and autocatalytic surface growth (k₂) were extracted. Comparing the k₁ (~10^-3) and k₂ (~10^-1) values supports a two-step mechanism of slow nucleation and fast autocatalytic surface growth.
