Thermodynamic Phase Control of Cu-Sn Alloy Electrocatalysts for Selective CO2 Reduction

Cu–Sn alloy catalyst can regulate CO 2 reduction reaction (CO 2 RR) intermediates. However, previous Cu–Sn alloy catalysts were limited in phase control. Here, we report thermodynamic based Cu–Sn bimetallic phase control and selective CO 2 RR.
