Template-directed electrosynthesis has been employed widely to prepare solids of defined dimension.It offers controllable routes to create nanostructures.We have developed one electrochemical method to fabricate one-dimensional metal oxide nanostructures.Here the electrochemistry strategy was employed to manipulate the pl] value within the pores of a template and the controlled growth of continuous one-dimensional metal oxide nanostructures was achieved.The strategy is exemplified by the growth of tin oxide nanotubes.At room temperature,the reduction of nitrate within pores was employed to electrogenerate hydroxide ions and drive local precipitation of stannic oxide nanotubes.Nanotubes displayed nearly uniform wall thickness along their entire length,were obtained within commercial track-etched polycorbonnte membranes.One-dimensional Zn/SnO2 core-shell nanostructures have been achieved by the further electrodepositinn of Zn within SnO2 nanotubes.
