Copper wires with seamless 1D nanostructures: Preparation and electrochemical sensing performance
چکیده انگلیسی
A Cu nanowire array seamlessly grown on Cu wire was prepared by electrochemical reduction of copper oxide nanowires grown by thermal oxidation. The morphology and structure of the nanostructured Cu wires were characterized via scanning electron microscope, transmission electron microscopy and X-ray diffraction spectroscopy. The seamless surface nanostructure offered a large surface area and improved conductivity. Electrochemical measurements demonstrated that the seamless nanowires structure could electrochemically reduce nitrate due to the improved conductivity between the active sites and the substrate. A linear response to nitrate ions over a concentration range from 50 μM to 600 μM (R2 = 0.9974) with a high sensitivity of 0.357 μA μM−1 cm−1 and low detection limit of 12.2 μM at a signal-to-noise ratio of 3, respectively, were obtained on the nanostructured copper wire. The influences of structure on electrochemical performance which are significant for the design of electrochemical sensor are discussed.
