Fig. 2: Synthesis and characterization of Cu and bimetallic CuGa.
From: Energy-efficient CO(2) conversion to multicarbon products at high rates on CuGa bimetallic catalyst
HR-TEM images and EELS-mapping of the (a) as-prepared and (b) post-CO2R Cu5Ga1 catalyst. The PXRD patterns (c) and Cu LMM Auger XPS spectra (d) of as-prepared Cu and Cu5Ga1 catalysts. e High-resolution Ga 2p XPS of as-prepared Cu5Ga1. f Ex-situ XANES at the Cu and Ga K-edge of as-prepared Cu and Cu5Ga1 catalysts. g FT-EXAF spectra at Cu K-edge of Cu and Cu5Ga1 catalyst. h FT-EXAF at the Ga K-edge of the as-prepared and post-catalysis Cu5Ga1. Cu foil, Cu2O, CuO, and Ga2O3 are shown as reference. Post-catalysis XAS of Cu5Ga1was performed immediately after electrocatalytic COR experiment. Relevant source data are provided in the Source Data file.
