(a) Schematic structure model of α-Ni(OH)2 single layer along c axis. The shadow represents the (001) plane. The third-nearest neighbor oxygen atom (O3) is situated in the adjacent layer (not shown); (b) Ni K-edge XANES spectra of the α-Ni(OH)2 nanosheets and their bulk counterpart; (c) Ni K-EXAFS oscillation functions k2x(k) and (d) the corresponding Fourier transforms.
