Fig. 4

a Scheme of support-induced restructuring of bimetallic PtCox/CNF catalyst for CO oxidation, ammonia borane hydrolysis, and hydrogen evolution reaction. The white, gray, red, yellow, and blue spheres represent the H, C, O, Pt, and Co atoms, respectively. b–d Normalized Co K-edge XANES spectra (b), FT Co K-edge k3-weighted FT-EXAFS spectra (c), and the corresponding WT-EXAFS of the Co K-edge signal (d) of the fresh PtCox/CNF catalysts. e–g\ Normalized Pt LIII-edge XANES spectra (e), FT Pt LIII-edge k3-weighted FT-EXAFS spectra (f), and the corresponding WT-EXAFS of the Pt LIII-edge signal (g) of the fresh PtCox/CNF catalysts.
