Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Figure 3 (Color online) High-resolution XPS spectra for (a) Ni 2p, (b) O 1s, and (c) C 1s of Ni@O–C and Ni@C. (d) N 2 adsorption-desorption isotherm curves of Ni-MOF, Ni@O–C, and Ni@C. (e) Ni K-edge XANES and (f) k 2-weighted EXAFS spectra of Ni@O–C, Ni@C, NiO, and Ni foil. WT diagrams of Ni K-edge EXAFS for (g) Ni foil, (h) NiO, (i) Ni@C, and (j) Ni@O–C.
