Magnetic nanowires (Ni) via chemical reduction method

This study discusses the synthesis of magnetic nickel nanowires (NiNWs) via a one-step chemical reduction method is reported. This technique is very straightforward and easy to be conducted by chemical reduction of the NiSO₄ solution with hydrazine in a basic solution. The objective of this research is to understand the influence of reaction time on the physical properties of synthesised NiNWs. In this study, the time reaction was varied from 10 minutes, 30 minutes and 60 minutes. X-ray diffraction (XRD) showed the NiNWs synthesised was polycrystalline with the orientation of crystals with (1 1 1) plane and subsequently with (2 0 0) and (2 2 0) planes. The effect of reaction time on the nanostructure of crystals produced was studied for surface morphology, crystal size and orientation using Scanning electron microscopy (SEM) analysis. Formation of different morphologies was discussed in detail.
