摘要：
Spiral silver nanobelts with a length of the order of tens of micrometers were fabricated by a simple galvanic replacement reaction of copper nanorods with an aqueous solution of AgNO3/Cu(NO3)(2). Observation revealed that the explicitly added Cu(II) ions enhanced the growth rate of silver nanobelts up to 11.7 mu m/s. An electrochemical mechanism based on the local concentration difference of Ag(I) ions is proposed to explain the process. (C) 2017 Elsevier B.V. All rights reserved.
