Electrochemically reducing CO 2 into fuels using renewable electricity is a contemporary global challenge that requires significant advances in catalyst design. Photodeposition techniques were used to screen ternary alloys of Cu‐Zn‐Sn, which includes brass and bronze, for the electrocatalytic reduction of CO 2 to CO and formate. This analysis identified Cu 0.2 Zn 0.4 Sn 0.4 and Cu 0.2 Sn 0.8 to be capable of reaching Faradaic efficiencies of >80 % for CO and formate formation, respectively, and capable of achieving partial current densities of 3 mA cm −2 at an overpotential of merely 200 mV.
