AFM characterization and electrochemical property of Ag nanowires by modified AAO template method

Ag nanowires as electrode materials were prepared from modified anodic aluminum oxide (AAO) template method by using dextrose as reductive, and the process of Ag nanowires growth was monitored by atomic force microscopy (AFM) and scanning electron microscopy (SEM). The structure and electrochemical properties of Ag nanowires were characterized by X-ray diffraction (XRD), UV–vis absorption spectra and cyclic voltammograms (CV) measurements. The results show that Ag nanowires prepared from AAO possessed typical face centered cubic structure with average diameter of 60 nm. Furthermore, the CV characterization reveals that Ag nanowires featured a pair of asymmetrical redox peaks with the position near 0.5 V and the microstructure was maintained in electrochemical reaction.
