FIGURE 3 | (A) K‐edge XANES and (B) K‐edge Fourier transform‐EXAFS spectra for R space of Co–Co, Fe@NCNF‐900. (C) K‐edge XANES and (D) K‐edge Fourier transform‐EXAFS spectra for R space of Fe–Co, Fe@NCNF‐900. (E) Fitting curve of the EXAFS of Fe–Co, Fe@NCNF‐900 in R‐space (inset: matching curve tracings within the q‐space domain). (F) EXAFS K‐space adjustments for the Fe–Co, Fe@NCNF‐900 catalysts. Wavelet transforms EXAFS of (G) Co–Co, Fe@NCNF‐900 and (H) Fe–Co, Fe@NCNF‐900 catalysts with its corresponding reference samples. EXAFS, extended X‐ray absorption fine structure; XANES, X‐ray absorption near‐edge structure.
