From: Improved electrochemical conversion of CO2 to multicarbon products by using molecular doping

Fig. 2

a Linear scan voltammetry (LSV) curves measured for different samples: N2SN, N3N, C2N, C3 functionalized Ag–Cu compared to pristine (P) Ag–Cu in CO2-saturated 0.5 M KHCO3 at electrochemical potential (V) from 0 to −1.4 V vs. RHE. Scan rate, 20 mV s−1. b Faradaic efficiency (FE) values for C2+ products on different samples at various potentials ranging from −0.3 to −1.4 V vs. RHE and measured in 0.5 M KHCO3. c j–V plots of the partial current densities for the C2+ products (ethylene and ethanol). d Relationships between the FE for C2+ and the total current density for all the catalysts. (e), Selectivity for C2+ products over hydrogen based on the ratio in FEs of C2+ and hydrogen. The error bars in b–e correspond to the standard deviation of three independent measurements.
