AI Article Synopsis
- A new and simple method is created to produce silver nanoparticles that are all the same size and in larger quantities by adding a tiny amount of Fe(3+) ions during the reaction of AgNO(3) with oleic acid and oleylamine.
- The process suggests that Fe(2+) ions help speed up the formation and growth of these nanoparticles by facilitating electron transfer between Ag(+) and Fe(2+).
- The Fe(2+) ions are generated when oleylamine reduces Fe(3+) ions during the reaction.
Article Abstract
A facile method is developed to prepare monodisperse silver nanoparticles in a much enhanced yield by adding a trace amount of Fe(3+) ions into the reaction of AgNO(3) with oleic acid and oleylamine. We propose that Fe(2+) ions speed up the nucleation and growth of silver nanoparticles due to the electron-transfer between Ag(+) and Fe(2+), in which Fe(2+) is from Fe(3+) reduced by oleylamine.
