(a.1, a.2, and a.3) cross-sectional TEM images of Ag/TiO2 nanocomposite wires, (a.4) high-resolution TEM images in the Ag and TiO2 layers (inset: crystallinity of Ag and TiO2, scale: 1 nm); (b.1, b.2, and b.3) cross-sectional TEM image of two-layer Ag/TiO2 nanocomposite cross architecture, (b.4) high-resolution TEM image of Ag and TiO2 layers (insets: crystallinity and FFT image of TiO2). (c.1–4) TEM image of Ag/TiO2 nanocomposite cross architecture and the corresponding EDS mapping images of Ag, Ti, and O, in that order.
