Figure 5. (A) Bi 4f XPS spectra of Bi50NC-900 and 5Pt/Bi50NC-900(H2); (B) Pt 4f XPS spectra of 5Pt/Bi0NC-900(H2) and 5Pt/Bi50NC-900(H2); (C) Bi L3-edge XANES; (D) Fourier-transformed EXAFS in the R-space of Bi; (E) Pt L3-edge XANES; and (F) Fourier-transformed EXAFS in the R-space of Pt of Bi50NC-900, 5Pt/Bi50NC-900(H2) and the reference sample. XPS: X-ray photoelectron spectroscopy; XANES: X-ray absorption near edge structure; EXAFS: extended X-ray absorption fine structure.
