(a) Schematic of the formation mechanism of Cu NWs. The Ni2+ and Cl− ions play critical roles in promoting the growth of high aspect ratio Cu NW. (b) and (c), SEM images of Cu NWs synthesized with Ni(OAc)2 and Ni(NO3)2 as precursors, respectively, which confirm the catalytic effect with the presence of Ni2+ ions.
