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. 3. (a-c) XPS spectra on Fe2p, Ni2p, and S2p, of NiFe-S, NiFe-0.6, and after long-term OER tested NiFe-S-0.6; (d) XANES E space spectra and e) EXAFS R space spectra at the Fe K-edge; (f) XANES E space spectra and g) EXAFS R space spectra at the Ni K-edge. The insets in (d) and (f) present the enlarged spectra of XANES.
