A Facile Fabrication of Silver-Coated Copper Nanowires by Galvanic Replacement

Figure 3

SEM images of the silver-coated Cu NWs for samples A (a) and B (b); the inset of (b) is a magnified image; EDS patterns of the silver-coated Cu nanowires for samples A (c) and B (d), respectively; (e) XRD patterns of the silver-coated Cu nanowires for samples A and B, and the PDF cards of cubic copper (red line, JCPDF number 96-710-1265) and silver (blue line, JCPDF number 01-087-0597) are provided for reference. The red rhombus represents the reflection of face centered cubic structure of metallic copper (JCPDF number 96-710-1265), while the blue star represents reflection of face centered cubic structure of metallic silver (JCPDF number 01-087-0597).
