Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Fig. 2. Characterization of as-prepared PtFe bimetallic catalysts. (a) H2-TPR profiles. (b) Pyridine-adsorbed IR spectra at 350 °C. (c) In-situ DRIFT spectra of CO adsorption on fresh (solid line) and reduced (dashed line) samples. Fe K-edge XANES (d) and EXAFS (e) spectra of 0.3Pt2Fe@NS sample under different treatment (F, R, S represent fresh, reduced, and spent sample after 30 h of PDH reaction, respectively). (f) Full-range EXAFS WT 2D plots for Fe-foil, Fe2O3, and 0.3Pt2Fe@NS catalyst.
