Fig. 2: Effect of interfacial wettability on electrochemical CO2RR performance.

From: Efficient wettability-controlled electroreduction of CO2 to CO at Au/C interfaces

Fig. 2

a Plot of average water droplet contact angles on different Au/C electrodes and photographs of water droplets on each electrode. b Geometric jCO and CO Faradaic efficiency of Au/C electrodes with various water CAs at −0.3, −0.4 and −0.5 V vs. RHE. Error bars represent the standard deviation of three independent experiments. c Cathode chronopotentiometry tests for Au/C-F, Au/C-P-0.5 and Au/C-P-2.5 in 1 M KOH at a constant current density of 100 mA cm−2 (without iR correction). Source data are provided as a Source data file.
