One-Pot Synthesis of High Aspect Ratio Copper Nanowires in Aqueous Solution

Abstract:

We report a one-pot, low temperature process for the synthesis of high-aspect ratio copper nanowires in aqueous solution for 1 hr. Ethylene diamine (EDA) was utilized to promote anisotropic reduction of Cu (II) by hydrazine. Cu nanowires with mean diameters around 90 nm and lengths exceeding 50 μm were synthesized using 180 mM EDA at 60°C, giving an effective aspect ratio of about 450. Without EDA, nanoparticle growth is observed. The synthesis temperature was also significant in limiting nanoparticle formation. Decreasing the temperature resulted to 1D growth and fewer nanoparticles.
