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.
