Figure 5: SEM images of template-freed Au nanostructures obtained with combined addition of EDTA and (a) 20 mM chloride, (b) 0.25 mM bromide, and (c) 0.25 mM iodide. The images on the right show magnified features of the obtained structures (porous Au NTs in (a), Au surface film in (b), and nanowires emerging from the surface film in (c)).
