Abstract
The kinetics of the formation of silver nanoparticles (AgNPs) by reduction of silver (I) with glucose are studied at different temperatures in aqueous micellar media. The reaction was carried out under pseudo-first-order condition by taking the [glucose] (>10-fold) the [Ag+]. The effect of [NaOH], [Ag+], [glucose] and [CTAB] are investigated. Rate of reaction enhance by increasing [OH-]. CTAB stabilized the rate of growth of nanoparticles and the rate of reaction increases with increasing in temperature. It was observed that nanoparticles are spherical, aggregated and poly dispersed. On the basis of kinetic data, a suitable mechanism is proposed and discussed for the silver sol formation. The particle size of silver sols is characterized by the transmission electron microscopic (TEM) and some physiochemical and spectroscopic tools.
