摘要：

Silver telluride nanowire arrays were synthesized by cathodic electrolysis into porous anodic alumina membranes from dimethyl sulfoxide (DMSO) solutions containing 0.1 M NaNO3, 5.0 mM AgNO3 and 6.0 mM TeCl4. XRD and SAED patterns of the nanowires were indexed to be a monoclinic structure of Ag2Te. TEM images show that the nanowires have smooth surfaces with uniform diameters. Near stoichiometric Ag2Te nanowires were obtained for potentials between -0.55 and -0.65 V vs. Ag/AgCl. Furthermore, the composition of the nanowires can be controlled continuously from Ag-rich to Te-rich mainly by changing the concentration of TeCl4 in the solutions.
