Characterization of the Ni in the SA Ni/Y2O3 nanosheets. a Aberration-corrected TEM image of the SA Ni/Y2O3 nanosheets. b EXAFS spectra of the Ni K-edge of the SA Ni/Y2O3 nanosheets, NiO and Ni foil. c Fourier transform (FT) of the Ni K-edge of the SA Ni/Y2O3 nanosheets, NiO and Ni foil. d Schematic model of the SA Ni/Y2O3 nanosheets and the corresponding FT-EXAFS fitting curves for the SA Ni/Y2O3 nanosheets. The scale bar in a is 2 nm
