A protocol for synthesis of ordered nickel nanostructure arrays with unique morphologies is described. In the present experimental findings a modified hydrazine reduction route has been described for fabrication of stable colloidal dispersions of nickel nanostructures in a lyotropic liquid crystalline medium using Triton X-100 as a nonionic surfactant. Different parameters, such as the concentrations of Ni, hydrazine hydrate and TX-100, were optimized using UV-vis spectrometry. The effects of temperature, pH and stability of Ni NPs were studied by aging the solutions for many days. The characterization studies include scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infra red (FTIR) spectroscopy.
