a LSV curves acquired in CO2- and N2-saturated 0.1 M KHCO3 solution on a rotating disc electrode at a rotation speed of 1600 rpm and a scan rate of 5 mV s−1. b Potential dependent Faradaic efficiencies for CO2RR on I: Ag1Cu NW (left), II: AgCu NW (middle) and III: Cu NW (right) (H-type cell). c Faradaic efficiencies for CO2-to-C2 products on I: Ag1Cu NW (left) and II: AgCu NW (right) in 1 M KOH electrolyte (flow cell). Error bars represent the standard deviation of three independent measurements. All voltage was recorded without iR correction. d The stability test of Ag1Cu NW acquired in a flow cell using 1 M KOH as the electrolyte at −1.0 V vs. RHE. The results of each potential in Fig. 2b, c were collected after one hour of continuous electrolysis.
