The cover shows a copper nanoparticle, which works in conjunction with adjacent nitrogen‐doped carbon nanospikes to electrocatalytically convert carbon dioxide to ethanol, through a 12‐electron reaction. The copper nanoparticle provides the initial adsorption site for carbon dioxide and mediates the first electroreduction to carbon monoxide. Next, two carbon monoxide molecules dimerize to form the carbon‐carbon ethyl backbone. Reactive sites on adjacent carbon nanospikes react with the dimer through one of the oxygen atoms, an arrangement which is believed to provide sufficient protection from complete electroreduction resulting in a preference for ethanol over ethane.
