Fig. 1. (a) Schematic diagram of Cu-SAs/TiO2 photocatalyst synthesis. (b) AC-HAADF-STEM image (insert is the intensity profiles taken from the rectangle-marked area), (c) HAADF-STEM image and the corresponding EDS element mappings of Cu-SAS/TiO2 sample. (d) Normalized Cu K-edge XANES spectra and (e) FT-EXAFS spectra of Cu-SAs/TiO2, Cu foil and bulk CuO. (f) XPS spectra of Cu-SAs/TiO2 and bulk CuO. (g) Raman spectra of Cu-SAs/TiO2 and pure TiO2 (insert is the enlarged view from 350 to 700 cm−1).
