“…The crystalline or amorphous structure is essentially different and compared from the experimental results and theoretical study. The process parameters employed in the deposition such as electrolyte concentration, deposition voltage and temperature are responsible for the structure and properties of nanowire arrays [20][21][22]. For onedimensional magnetic metal or metal oxide materials, the properties of the nanowires array is related to the character of individual nanowire and the periodicity or the symmetry of nanowires.…”

Electrochemical deposition has been widely used for synthesis of metal nanowires (NWs) on the porous template. In this paper, the effect of potential and electrolyte concentration on cobalt (Co) NWs formation through porous anodic alumina template has been investigated using direct-current electrodepostion at 0.75~2 V together with the high 0.5 M and low 0.1 M cobalt sulfurate based electrolyte. Scanning electron microscopy and grazing incidence X-ray diffraction were used to examine the nanostructure, morphology and phase of Co NWs. The current vs time curve was recorded for understanding the growth behavior. Too low potential of 0.75 V is not favored for Co NWs formation due to insufficient driving force while too high potential of 2 V ruins the NWs growth owing to hydrogen generation in reduction reaction. The uniform crystalline Co NWs can be obtained by the proper potential of 1V and concentration of 0.5 M at an average growth rate of 964 nm/min.

“…Arrays of uniform nanowires are produced using a porous membrane. Different types of nanowires have been obtained by this method: pure metals, 27 alloys, 28,29 oxides, 30,31 and semiconductors. 32 Core-shell nanowires are also synthesized initially by a superposition of two different types of semiconductors for electronic applications.…”

Synthesis and characterization of copper–silver core–shell nanowires obtained by electrodeposition followed by a galvanic replacement reaction in aqueous solution; comparison with a galvanic replacement reaction in ionic media

Copper-silver core-shell nanowires were synthesized using a combination of two methods: electrodeposition in a polycarbonate membrane as a template for the synthesis of a copper core and a galvanic replacement reaction for the elaboration of a silver shell. A comparative study between aqueous and ionic liquid media was performed for the silver shell elaboration. The kinetics of the reaction in both media was monitored by using energy dispersive x-ray spectroscopy. The shape and size of the nanowires were observed by both scanning electron microscopy and transmission electron microscopy. The core-shell structure was determined by electron energy loss spectroscopy analyses for the Cu 90 Ag 10 composition. A homogenous silver shell was formed in aqueous media. Whereas in ionic solvent, well defined silver crystals were obtained at the surface of the nanowires but without a total formation of a silver shell structure.

“…Template synthesis has been proven to be a versatile and simple approach for the preparation of metal nanowires [10,11]. Electro-deposition technique is a strict control of the nanowire length and arrangement of segments with different compositions along the nanowire length [12,13,14]. Anodized porous aluminum oxide (AAO) template-based electro-deposition seems to be the most efficient way.…”

Highly ordered copper nanowire arrays were prepared by electrolytic deposition using porous anodic aluminum oxide (AAO) as template. The technique of removing the barrier layer of the AAO template by the pore widening procedure was investigated. The quality of the Au conducting layers sputtered at the bottom side of the AAO template was also studied. The direct current (DC) electrodeposition of copper nanowire arrays was performed efficiently above the Au layer inside the pores. The morphology of the copper nanowires was characterized by scanning electronic microscopy (SEM) and the composition of Cu nanowires was confirmed by energy dispersive X-Ray spectroscopy (EDS). The results showed that the best condition was found to be in phosphoric acid (6%wt) for 10 min to remove the barrier layer completely. Au layer was uniform and dense after sputtering for four times. Copper nanowire arrays were successfully prepared by three-electrode and two-electrode cell electro-deposition, but the nanowire arrays were more ordered by using three-electrode cell and the length of nanowires was more uniform. The diameter of a single Cu nanowire is less than 100 nm with the length up to around 10 μm, and the nanowires are well arranged in arrays.
