Electrodeposition of Single Crystalline Co<sub>56.48</sub>Ni<sub>43.52</sub> Alloy Nanowires in AAO Template

Abstract

Single crystalline cobalt nickel (Co-Ni) alloy nanowires are successfully fabricated using direct current (DC) electrodeposition with in the nanopore of highly ordered anodized aluminum oxide (AAO) template. SEM studies show that the average diameter of the alloy nanowires is approximately equal to 50 nm which corresponds to the pore size of the AAO template. Energy-dispersive X-ray (EDX) analysis confirmed that the Co-Ni alloy nanowires are deposited with 56.48:43.52 atomic ratios. We believe that at high potential the current density of Co nanowires is higher than depositing Ni nanowires which are clear by polarization curves, so content of Co increases in deposited Co56.48Ni43.52 alloy nanowires. Single crystalline Co56.48Ni43.52 alloys can be useful in future to compose and synthesize other metal nanostructures via template-based electrodeposition.
