Fig. 4: X-ray absorption spectroscopy data.
From: A pyridinic Fe-N4 macrocycle models the active sites in Fe/N-doped carbon electrocatalysts
XANES spectra (a) and expanded main-edge region (inset), k2-weighted Fe k-edge EXAFS spectra (b) and k2-weighted Fourier transform Fe EXAFS spectra (c). The energy values of the vertical lines and the alphabetical labels in (a) are taken from reference70. Fe-N-C is shown in black, [(phen2N2)Fe]2O in blue, [(OEP)Fe]2O in orange and [(PcFe)]2O in aqua.
