Title: Controlled synthesis and magnetic properties of Ni nanotubes and nanowires

Abstract

Graphical abstract: TEM images of the as-prepared Ni nanotubes and nanowires. - Highlights: • Ni nanotubes and nanowires are synthesized by a convenient sol-gel autocombustion method with the assistance of AAO templates. • The products having tubular or wire-like morphologies can be perfectly controlled by adjusting the experimental conditions. • The synthetic mechanism is discussed. • Magnetic measurements indicate that both the Ni nanotubes and the Ni nanowires possess superparamagnetism at room temperature. - Abstract: Ni nanotubes and nanowires with an average diameter of about 140 nm are synthesized by a template-assisted sol-gel autocombustion method using nickel nitrate, citric acid and ammonia as the starting materials. The anodic aluminum oxide templates are prepared by a facile anodizing method. By adjusting the experimental conditions in the sol-gel process, the final products having tubular or wire-like morphologies can be perfectly controlled. Transmission electron microscope characterization indicates that the Ni nanotubes are very friable and can be easily broken into pieces of short nanotubes, but the Ni nanowires are compact and have very high aspect ratios. Magnetic measurements indicate that both the Ni nanowires and the Ni nanotubes possess superparamagnetism at room temperature.
