Abstract
This work describes a procedure for the fabrication of noble metallic nanowires, such as gold, silver and plutinum. Metallic nanowires were formed and connected to a network structure uniformly covering a 2-dimensional space by carefully controlling the concentration of reducing reagent in the synthetic method for metallic nanoparticles. It is considered that the decrease of the reducing agent, which acts as well as capping agent, reduces the electrostatic repulsion of preliminary nanoparticles, resulting in the fusion of the nanoparticles to form nanowires. In the case of gold, it was also found that gold ions played an important role in forming and stabilizing the shape of gold nanowires. This method for synthesizing 2-D metallic nanowires is simple and expected to be used as a general methodology for the synthesis of other metallic nanowires.
