Large‐Scale Synthesis of Ultra‐Small‐Sized Silver Nanoparticles

Large scale for small size: We report a large-scale synthetic method to produce uniform and ultra-small-sized Ag nanoparticles (see picture) with good productivity. This method is simple and efficient. It produces Ag nanoparticles within 20 min by heating a reaction mixture containing only three chemicals. The size of the nanoparticles is controlled by varying the heating rate.
