文摘

A highly efficient direct electrodeposition method was used to prepare Co-Cu alloy nanotubes in an anodicalumina template without modification. The morphology and structure of as-prepared Co-Cu nanotubes wereexamined by scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. Theformation mechanism of the tubular nanostructure is discussed. It was found that the template directedelectrodeposition of Co-Cu at a large current density can result in the highly efficient growth of nanotubesand that the growth rate as well as the wall thickness of the nanotubes can be controlled via the currentdensity of electrodeposition. Magnetic measurements of the Co-Cu nanotube array show that the nanotubesare ferromagnetic at room temperature and may find potential applications in the fields of biological separationand drug delivery.
