a Normalized Fe K-edge X-ray absorption near-edge structure (XANES) spectra and b Fourier-transformed extended X-ray absorption fine structure (FT-EXAFS) spectra for Fe K-edge of Fe–N–C, FeBi–N–C, and reference samples. c Wavelet-transform (WT) contour plot in the Fe K-edge EXAFS spectra of Fe–N–C and d FeBi–N–C. e Normalized Bi L3-edge XANES spectra and f FT-EXAFS spectra for Bi L3-edge of Bi–N–C, FeBi–N–C, and reference samples. g WT contour plot in the Bi L3-edge EXAFS spectra of Bi–N–C and h FeBi–N–C.
