Fig. 4: Structural characterization of Cu(OD)0.8Ag0.2 catalyst after CO reduction reaction.

From: Weak CO binding sites induced by Cu–Ag interfaces promote CO electroreduction to multi-carbon liquid products

a TEM image of Cu(OD)0.8Ag0.2 catalyst cross-section cut by FIB. b Electron diffraction pattern of Cu(OD)0.8Ag0.2 catalyst shown in a. c HAADF-STEM image and corresponding EDS mapping of Cu and Ag. d HAADF-STEM image and the corresponding atomically resolved EDS mapping of Cu and Ag at the selected interface area. The atomic ratio between Cu and Ag at the interface (i.e., the area within the green box) was determined to be 1.12:1.
