Abstract :
Present study describes synthesis of highly active and ordered nanoscale structures of nickel catalysts. The study reveals efficient catalytic activity for the degradation of toxic and lethal organic dye Eosin-B (EB). The stable colloidal dispersions of ordered nickel nanostructures (Ni NSs) arrays were prepared via modified hydrazine reduction route with unique morphologies in a lyotropic liquid crystalline medium using Triton X-100. The characterization studies like optimization of various parameters for preparation of nanoscale nickel structures, surface binding interactions, size and morphologies of Ni NSs were carried out by UV-Visible Spectroscopy, Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD) Analysis.
