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.

Abstract EFAB (“Electrochemical FABrication”) is a new micromachining process utilizing an innovative “Instant Masking” (IM) technique to electrochemically deposit an unlimited number of metal layers for microfabrication. Through this approach, high-aspect-ratio microstructures with arbitrary 3-D geometry can be rapidly and automatically batch-fabricated at low temperature (< 60 °C) using an inexpensive desktop machine. IC-MEMS integration can also be carried out by this low temperature process.

Nitrophenol Degradation

{100}-faceted copper nanostructures with different morphology of nanowires and nanocubes have been prepared by one-pot method. The electroactivity of Cu nanowires and nanocubes was evaluated by degradation of p-nitrophenol. As-prepared copper nanowires exhibit higher catalytic activity for p-nitrophenol degradation than copper nanocubes, and outperform most of Cu catalysts reported in literature. Electrochemical reductive reaction of p-nitrophenol is shown to be kinetically first-order.

ABSTRACTZnO nanorods were grown up from as-deposited ZnO film on which the zinc self-catalysts generated by a novel reducing method. Well aligned ZnO nanorods with a uniform high aspect ratio were grown up on multi-annealed samples. The length of nanorods depended significantly on the reaction time in the hydrothermal synthesis.
