Figure 5. (a) Normalized Co K-edge XANES spectra of Co foil, CoO, Co3O4, Co@C−N, Co2P@C-NS, and Cu/Co2P@C-NS-36 nm. (b) Fouriertransformed (FT) k2-weighted EXAFS spectra for the Co K-edge of Co foil, CoO, Co3O4, Co@C−N, Co2P@C-NS, and Cu/Co2P@C-NS-36 nm. Corresponding Co K-edge EXAFS fitting curves of Co@C−N, Co2P@C-NS, and Cu/Co2P@C-NS-36 nm in panels (c) R space and (d) k space. (e) Wavelet transform k3-weighted EXAFS spectra of different samples.
