Photocatalytic reaction efficiency of the fabricated samples: (a) UV-vis absorbance spectra of MB with three-layer Ag/TiO2 nanocomposite cross architecture under visible-light irradiation every 15 min. (b) UV-vis absorbance spectra of MB with two-layer Ag/TiO2 nanocomposite cross architecture under visible-light irradiation every 15 min. (c) UV-vis absorbance spectra of MB with Ag/TiO2 nanocomposite wires under visible-light irradiation every 15 min. (d) Photocatalytic decomposition of MB solution with and without the fabricated samples under visible-light irradiation every 15 min (Ag/TiO2 nanocomposite wires, film, and two- and three-layer Ag/TiO2 nanocomposite cross architectures).
