Fig. 2

a Schematic illustration for the synthesis of M. b-NiCu@CdS. b SEM images of M. b-NiCu@CdS (the inset image shows bare M. b). c−g TEM image of M. b-NiCu@CdS (c) and the corresponding EDS mapping of Cd (d), S (e), Ni (f) and Cu (g). h CLSM image of M. b-NiCu@CdS. i−j K-edge XANES spectra of Ni, Cu and the references (i) and the corresponding Fourier transforms of k2-weighted EXAFS spectra (j). k Average bond lengths and coordination numbers in the first coordination shells of Ni and Cu atoms obtained by EXAFS spectral curve fitting. Scale bars: 1 μm in b, 2 μm in the insert image, 500 nm in c–g, and 10 μm in h. Source data are provided as a Source Data file.
