Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Figure 2. Electronic and fine structural characterizations. XPS results of (a) Pd 3d and (b) Cu 2p spectra for PdCuN/Al2O3 and PdCuC/Al2O3 catalysts; (c) normalized Pd K edge XANES spectra and (e) FT-EXAFS spectra of PdCuN/Al2O3 and PdCuC/Al2O3 catalysts, with Pd foil and standard PdO samples as references; (d) normalized Cu K edge XANES spectra and (f) FT-EXAFS spectra of PdCuN/Al2O3 and PdCuC/Al2O3 catalysts, with Cu foil and standard CuO samples as references.
