Universal synthesis of pure-phase IB-group Sn-based alloys with modulable electrocatalytic CO reduction products

We present a universal preparation method for synthesizing a range of pure-phase IB-group Sn-based alloy catalysts (Cu 3 Sn, Ag 4 Sn, and AuSn) for electrochemical reduction of CO 2 to C 1 product. The selectivity can be widely adjusted by altering metal composition and potential, improving the understanding of the structure-activity relationship in various Sn-based alloys. A universal method for synthesizing a range of pure-phase IB-group Sn-based alloy catalysts (Cu 3 Sn, Ag 4 Sn, and AuSn) for electrochemical reduction of CO 2 .
