Figure 2. Structure and properties of catalysts (A–C) XPS spectra of the samples. (A) O 1s, (B) Co 2p, and (C) Sn 3d. (D) Co K-edge XANES spectra of Co3O4x and 1.0-Sn/Co3O4x along with those of Co foil, CoO, and Co3O4 as reference standards. (E) Fourier transformed EXAFS spectra of Co3O4x and 1.0-Sn/Co3O4x. (F) Sn K-edge XANES spectra of 1.0-Sn/Co3O4x along with those of Sn foil, SnO, and SnO2 as reference standards. (G) Fourier transformed EXAFS spectra of 1-Sn/Co3O4x, SnO, SnO2, and Sn foil. (H) Corresponding WTs for the k3-weighted Sn K-edge EXAFS signals of 1.0-Sn/Co3O4x, SnO, SnO2, and Sn foil.
