Electrocatalytic conversion of carbon dioxide (CO 2 ) has recently received considerable attention as one of the most feasible CO 2 utilization techniques. In particular, copper and copper‐derived catalysts have exhibited the ability to produce a number of organic molecules from CO 2 . Herein, we report a chloride (Cl)‐induced bi‐phasic cuprous oxide (Cu 2 O) and metallic copper (Cu) electrode (Cu 2 O Cl ) as an efficient catalyst for the formation of high‐carbon organic molecules by CO 2 conversion, and identify the origin of electroselectivity toward the formation of high‐carbon organic compounds. The Cu 2 O Cl electrocatalyst results in the preferential formation of multi‐carbon fuels, including n ‐propanol and n ‐butane C3–C4 compounds. We propose that the remarkable electrocatalytic conversion behavior is due to the favorable affinity between the reaction intermediates and the catalytic surface.
