Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Fig. 2. The TEM image (a) and HRTEM image (b) of FCDs; (c) The FTIR spectrum of FCDs; (d–f) The high-resolution XPS of C 1s, N 1s, and O 1s spectra of FCDs, respectively. (g) The 1HNMR spectra of ZnSO4, FCDs and FCDs/ZnSO4 aqueous solutions; (h) The normalized Zn K-edge XANES spectra of ZnSO4 electrolyte with and without the FCDs additive. The inset is the enlarged Zn K-edge XANES spectra; (i) The EXAFS spectra in R space.
