From: Bimetallic core/shell nanoparticle-decorated 3D urchin-like hierarchical TiO2 nanostructures with magneto-responsive and decolorization characteristics

Figure 4

Typical morphology, structure, and composition of the hierarchical Co@Ag/TiO 2 . SEM images (a, b), TEM images (c, d), and high-resolution TEM images (e, f), the local elemental mapping (g), and corresponding EDX spectra of the nanoparticles on the tips of TiO2 nanorods (h) for the 3D urchin-like hierarchical Ag@Co/TiO2 nanostructures. (Scale bar = 1 μm for (a-b); scale bar = 500 nm for (c); scale bar =200 nm for (d); scale bar = 100 nm for (e); scale bar = 20 nm for (f-g)).
