We describe an unconventional electrochemistry approach to the preparation of silver nanowires. By the electrodeposition in the dilute solution without supporting electrolyte, silver nanowires with diameter 10-50 nm and length up to several mu m have been synthesized. It was found that the absence of the supporting electrolyte played a key role in the formation of silver nanowires, and the products from the solution without supporting electrolytes were very different from those with supporting electrolytes. A possible mechanism concerning the transportation of silver ions by electro-migration and the diffusion was proposed. (C) 2006 Elsevier B.V. All rights reserved.
