Novel 1D Ni-Ag composition nanostructure: Synthesis, properties and antioxygenation improvement

Nickel nanochains assembled with submicrometer-sized flowers were synthesized through a mild hydrothermal method without any template and surfactant. Subsequently, nickel-silver metal composition nanostructures were also prepared by taking advantage of reducing property of nickel metal. The resulting chains superstructures were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, high-resolution transmission electron microscopy and the thermogravimetric analysis (TGA) measurements. This synthesis of such hierarchical structures implies a simple and inexpensive way to prepare bimetallic composite superstructures on a large scale. Furthermore, antioxygenation properties of these bimetallic composites could be improved drastically.
