Morphology of the nanoporous Ag-Cu@Ag core-shell alloy. (a–c) SEM images of the 24 h dealloyed sample with different magnifications. Inset in (a) is the optical photograph of the 24 h dealloyed Zr-Cu-Ag-Al-O ribbon sample. (d) XRD spectra of the as-prepared (line a) and the 24 h dealloyed (line b) Zr-Cu-Ag-Al-O ribbon samples. (e) Bright field TEM image of the 24 h dealloyed Zr-Cu-Ag-Al-O ribbon sample. (f) The SAED pattern of (e).
