      abstract     = {The electrochemical reduction of carbon dioxide to ethanol
                      is a promising way to make CO2 electrolysis economically
                      feasible. In this work, a bimetallic catalyst of silver and
                      copper is synthesized, and the effect of its copper content
                      on the formation of ethanol is analyzed. By decreasing the
                      near-surface copper content from 99 to $45\%$ (measured by
                      XPS) at a current density of −20 mA cm–2, the Faradaic
                      efficiency of ethanol could be enhanced from 5 to $23\%.$
                      Moreover, we show that with excess of CO, due to a lower
                      copper and a higher silver near-surface content, the
                      formation of ethanol is favored over ethylene.},
