Large-Scale Cu Nanowire Synthesis by PVP-Ethylene Glycol Route

Figure 6

SEM images of Cu nanostructures obtained during heating at different reaction times: (a) 0, (b) 60, (c) 100, (d) 110, (e) 120, and (f) 240 min. Insets in (b) and (c) correspond to the dissolution of the synthesized spherical Cu₂O particles and the formed Cu₂O cubes, respectively. (g) TEM image of Cu NWs showing the direction of growth. (h) SAED pattern of the Cu NWs.
