Metallic nanoparticles are of great interest because of the modification of properties observed due to size effects, modifying the catalytic, electronic, and optical properties of the monometallic nanoparticles.The polyol method has been reported to produce small nanoparticles as the final product, easily changing composition and surface modifiers. This technique does not require an additional reducing agent since the solvent by itself reduces the metallic species. Oxygen reduction reaction is one of the most important electrochemical reactions in electrochemical energy conversions, using Pt nanoparticles as catalyst.
