| Abstract: In this paper, highly ordered anodic aluminum oxide (AAO) template with hexagonal close-packed arrays was successfully fabricated through a two-step anodization process. Ag nanowire arrays with high aspect ratio were prepared using cyclic voltammetry within the confined nanochannels of AAO template. In addition, standing Ag nanowire arrays free-support of templates were also fabricated successfully by cyclic voltammetry method. The micrographs and crystal structures of Ag nanowires were studied by field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD). FESEM observation showed that the Ag nanowire arrays with high aspect ratio lie orderly on the surface of the substrate. The diameter of the Ag nanowire is about 60 nm and the length up to 30 μm or more. While the controlled nanowire arrays exhibit highly ordered structure in large area and the standing Ag nanowire in the array has the length of 1 μm and good orientation. XRD results illustrated that the Ag nanowires in the arrays deposited by cyclic voltammetry method have a face centered cubic structure and are preferentially oriented in the (220) direction. |
