Fig. 2: CO2RR performance over Sb1Cu catalysts and Cu.
From: Selective CO2 electrolysis to CO using isolated antimony alloyed copper
a FEs of all CO2RR products at different current densities and the corresponding j-V curve of Sb1Cu-5. b In situ DEMS measurement of (up) CO and (down) C2H4 production during CO2RR on Cu and Sb1Cu-5 catalysts. c Stability test at −100 mA cm−2 current density in MEA for over 10 h, indicating an average CO FE of approximately 95%, as estimated by GC analysis. Performance metrics of different reported CO2RR-to-CO d Cu-based and e non-Cu-based catalysts. Comparison of product FEs on f Cu, g Sb, and h Sb1Cu-1.5. The error bars correspond to the standard deviation of three independent measurements.
