The Synthesis of Gold Nanoparticles in Chloride-Citrate Water Solutions Obtained Using the Electrochemical Method

摘要

The kinetics and the mechanism of electrode processes that occur on gold in acid chloride-citrate solutions have been studied. It was established that these solutions provide the anode dissolution of gold with the formation of the mixed polyatomic metal ions in which gold is univalent. The reduction of obtained gold ions by reducing agents, in particular by hydrogen peroxide and refined sugar resulted in the formation of stable gold nanoparticles. Due to their nanosizes and high biological activity such particles have a high potential for the hands-on use in different spheres of the vital activities of human beings.
