a–c HAADF-STEM images and corresponding EDS elemental maps of Ag0.25-Cu0.75 (a) Ag0.33-Cu0.67 (b) Ag0.5-Cu0.5 (c) after restructuring. Insets show schematics of the reconstructed Ag-Cu interface. d–f XPS spectra of Ag0.25-Cu0.75 (d) Ag0.33-Cu0.67 (e) and Ag0.5-Cu0.5 (f) before and after electrolysis. g A top-view of the concentration and flux distribution of *CO on Ag-Cu heterostructures with different Ag densities via the FEM simulation. h Proposed restructuring mechanisms of Ag-Cu heterostructures with different Ag densities.
