Fig. 2: Comparison of C1 product and H2 formations.
From: Oxygen induced promotion of electrochemical reduction of CO2 via co-electrolysis
The partial current densities of C1 products and H2 measured at 100% CO2, 10% O2 + 90% CO2, and 20% O2 + 80% CO2 are compared at different potentials of a −0.75 VRHE, b −0.80 VRHE, c −0.85 VRHE, d −0.90 VRHE, e −0.95 VRHE, and f −1.0 VRHE. The numbers stand for the enhancement relative to the rates at pure CO2. The error bars represent the standard deviation from at least three independent measurements.
