Extended Data Fig. 4: Carbon selectivity and CO/CO2 conversion.
From: Coverage-driven selectivity switch from ethylene to acetate in high-rate CO2/CO electrolysis
Product selectivity (left Y axis) and CO/CO2 conversion (right Y axis) as a function of applied current density over CuO nanosheet catalyst measured in 0.1 M KOH under (a) pure CO2 feed, (b) CO/CO2 (1:3) co-feed, (c) CO/CO2 (1:1) co-feed, (d) CO/CO2 (3:1) co-feed, (e) pure CO feed, and (f) 0.6 MPa pure CO with a flow rate of 30 mL min−1, as well as 1 M KOH under 0.6 MPa pure CO with a flow rate of 30 (g) and 60 (h) mL min−1. For pure CO2 electrolysis in (a), only C2+ products were accounted for the carbon selectivity. Error bars represent the standard deviation from three independent measurements.
