摘要：

Silver nanoparticles are prepared by reducing Ag(+) ions with sodium borohydride in aqueous solutions containing carbonate ions (5 x 10(-5)-1 x 10(-2) mol l(-1)). It is established that carbonate ions represent an efficient stabilizer that provides nanoparticles with electrostatic protection via the formation of an electrical double layer. The maximum stability of a silver dispersion is observed at a carbonate ion concentration of 1 x 10(-3) mol l(-1). The average size of silver nanoparticles is 10.0 +/- 2.5 nm. The formation kinetics of silver nanoparticles is described by an equation for a first-order reaction with a rate constant of 2.3 x 10(-3) s(-1) (+/- 20%).
