The electroreduction of CO strongly depends on the nature and concentration of the electrolyte cations. In their Research Article on page 4464, B. Xu, Q. Lu, and co‐workers demonstrate that high concentrations of the cation (Na + ), rather than OH − , are the predominant factor affecting the formation of C 2+ products. The conclusions are supported by experiments in which a fraction or all of the Na + ions were chelated by a crown ether. The chelated Na + ion is depicted as a planetary system.
