(a) Bare ZnO NWs, (b) ZnO/Fe NWs, (c) ZnO/Fe/Ag(NPs) NWs, and (d) ZnO/Ag(NPs)/Fe NWs. Insets at top right corner in (a–d) display the typical high-magnification SEM images of a single NW. Insets at lower left corner in (c,d) show histograms of particle diameter distributions in the ZnO/Fe/Ag(NPs) and ZnO/Ag(NPs)/Fe NWs.
