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. The characterizations of Co/C and Co-N/C samples. (a) XRD patterns, (b) Raman spectra, high-resolution XPS spectra of (c) N 1 s, and (d) relative content of N species determined by XPS analysis. (e) Co K-edge X-ray absorption near-edge spectra (XANES) spectra (the orange area highlights the near-edge absorption energy), (f) wavelet transform (WT), and (g) Co K-edge extended X-ray absorption fine structure (EXAFS) profiles of Co/C, Co-N/C, and reference sample Co foil. (h) N K-edge XAFS spectra of Co/C and Co-N/C samples.
