ABSTRACT
This work explores the fabrication and characterization of Ni and NiO nanowires. Ni nanowires were fabricated using electrochemical deposition into an AAO template. The techniques of sol-gel synthesis and template-directed growth are merged for the formation of NiO nanowires. When the porous templates of aluminum oxide were dipped in these solutions, the solution was captured in the pores. These templates were then heated at elevated temperatures to harden the nanowires. Different characterizations of Ni and NiO nanowires were carried out using, SEM, XRD, and VSM to find out the morphology, behavior, and magnetic characteristics of nanowires formed. This new method for the preparation of NiO nanowires may be significant for the gas sensors to various engineering materials.
