Abstract The electrochemical CO 2 reduction reaction (CO RR) into valuable chemicals represents an effective approach for realizing carbon neutralization goals. Copper oxide‐derived catalysts are particularly promising due to their tunable electronic structures. In this study, we focused on investigating the Ag Cu O 3 model catalyst and a mixture of CuO with identical metal molar ratio (denoted as M–CuAgO). Electrochemical RR tests revealed that exhibited selectivity towards ethanol, while M–CuAgO showed no multi‐carbon products. Characterizations post‐reaction materials differences in specific crystal structures two catalysts. Further X‐ray photoelectron spectroscopy (XPS) analysis demonstrated structure, after reaction, facilitated transfer electrons from Ag, thereby promoting formation This work underscores significance structural design precatalysts opens up new avenues high‐performance
