Aqueous synthesis of flower-like nickel nanostructures under the induction of magnetic field

This work focused on a synthetic method to produce flower-like nickel nanostructures under the induction of magnetic field. Flower-like nickel nanostructures were obtained by using nontoxic reactants, nontoxic solvents, and low reaction temperature. It was improved, comparing to other methods previously described. The XRD patterns showed an fcc-like structure and the thermal analysis showed the purity of flower-like nickel nanostructures. Flower-like structure was assigned by high-resolution scanning electron microscopy (HRSEM). The magnetic field induced the construction of nickel nanopowders. We also found the resultant nickel nanostructures as catalyst promoted the combustion of ammonium perchlorate.
