Figure 2. High-resolution XPS spectra of (a) Co 2p, (b) Zn 2p, and (c) S 2p of Co9S8@ZnS/C, ZnS/C, and Co9S8. (d) Co K-edge XANES spectra. (e) FT-EXAFS spectra of the K-edge of Co9S8@ZnS/C compared with standard references (Co foil, CoPc (cobalt phthalocyanine), Co3S4, and Co3O4). (f) Wavelet transform (WT) plots for Co in Co9S8@ZnS/C and Co3S4. (g) Synchrotron Zn K-edge XANES spectra. (h) Zn K-edge k3-weighted FT-EXAFS spectra of Co9S8@ZnS/C compared with standard samples (Zn foil, ZnPc (zinc phthalocyanine), ZnO, and ZnS). (i) WT plots for Zn in Co9S8@ZnS/C and ZnS/C.
