Abstract

Gold-silver bimetallic nanoparticles (including alloy, core-shell and nanocage structure) are good noble metal nanomaterials with unique properties which have widespread applications in electronic, photonic, chemical and biological fields. Especially in recent years, more and more investigators are motivating this advanced material rapidly towards surface-enhanced raman scattering(SERS) and high catalytic activity of carbon monoxide oxidation at room temperature. Herein, we outlined the current research advances of gold-silver bimetallic nanoparticles in synthesis, optical properties, surface-enhanced raman scattering application and catalytic activity, with the aim of stimulating more research to achieve more useful application as soon as possible.
