a Normalized X-ray absorption near-edge structure spectroscopy (XANES) spectra of hcp Ni NSs (purple line), fcc Ni NPs (blue line), Ni foil (green line), and NiO (yellow line) recorded at the Ni K-edge. b Enlarged view in (a). c Fourier transforms of Ni K-edge extended X-ray absorption fine structure spectroscopy (EXAFS) spectra of hcp Ni NSs, fcc Ni NPs, Ni foil, and NiO. d-f Wavelet transform (WT) of the k3-weighted EXAFS at the Ni K-edge of hcp Ni NSs, fcc Ni NPs and Ni foil. g Schematic diagram of the atomic stacking model of hcp Ni NSs along a, b, and c directions.
