Abstract

Silver nanoparticles (AgNPs) were prepared by means of the polyol method in the absence of stabilizing polymers. To accomplish this objective, AgNO ₃ was added to ethylene glycol in the presence of NaOH (1 mol.L ^-1), the suspension formed was irradiated with a microwave source for 60 seconds at a power of 465 watts. It was found that under these conditions AgNPs of sizes between 4-18 nm are formed. Also the results indicate that part of the ethylene glycol is oxidized to carbonyl compounds that reduce the Ag ⁺. These organic compounds are adsorbed on the surfaces of AgNPs, forming a protective flm that prevents their aggregation.
