Abstract

A facile and completely green route to synthesize Au nanoparticles by mixing the Au(III) ions-dissolved rice wine and soda at a slightly elevated temperature in the absence of extra protective agents was developed. Rice wine was used as a solvent and a reducing agent. Also, soda not only functioned as a protective agent but also played a role of base catalyst No extra protective agents are needed. From the analyses of UV/VIS absorption spectra, TEM, and XRD patterns, the formation of Au nanoparticles was recognized. The appropriate pH and temperature were around 6.5 and 25-55°C, respectively. The resultant solution was quite stable. No precipitation occurred even after several months. In addition, rice wine and soda are often used as the additives of drinks or foods, and are easily obtained in our daily life. So, it becomes possible that people can easily make the Au nanoparticles at home by the route proposed in this work.
