Figure 2. K-edge EXAFS spectra of MnFeCoNi/NC and CrMnFeCoNi-(CrOx)1/NC in R space: (A) Cr, (B) Mn, (C) Fe, (D) Co, and (E) Ni; (F) Cr pre-edge and (G) EXAFS spectra of CrMnFeCoNi-(CrOx)1/NC, Cr foil, and CrO3 in R space; (H) WT-EXAFS k-R contour plots of CrMnFeCoNi-(CrOx)1/NC, Cr foil, and Cr2O3. EXAFS: Extended X-ray absorption fine structure; WT-EXAFS: wavelet transform-EXAFS.
