Description

A new method to form a single gold nanoparticle (Au NP) is introduced. In our method, a single Au NP is spontaneously formed on the surface of a nanometer-sized platinum (Pt) electrode under open circuit potential. The single NP has been characterized by using Scanning Electron Microscopy and electrochemical methods. Electrochemical studies reveal that the small Au particle has extraordinary stability compared with that of a bulk Au phase. The extra stability of the Au NP is attributed to the formation of alloy with the Pt substrate.
