How carbon oxides are reduced by copper electrodes is a mystery. In their Communication on page 7282 ff. , F. Calle‐Vallejo and M. T. M. Koper use DFT calculations to elucidate a mechanism for the electroreduction of CO on Cu(100) to C 2 species. The electron‐transfer‐mediated coupling of CO molecules is found to be the rate‐limiting step. The most abundant C 2 products, namely ethylene, ethanol, and acetaldehyde, are formed in a common pathway. This mechanism explains why the formation of C 2 species is pH‐independent.
