Fig. 3

a Schematic of the eCO2R system configuration. b Schematic of chemical reactions with a cathode, anode, and bipolar membrane. c CO FEs for Ag/C measured with various applied current densities in monoethanolamine, diethanolamine, and TREA. d CO FEs for Ag NP, Ag/C, coral-Ag, and coral-Ag/C in 3 M TREA. e SEM images (scale: 500 nm) and contact angles for all Ag electrodes. f CO FEs for Ag/C measured with various membranes, including an anion exchange membrane, cation exchange membrane and bipolar membrane, in 3 M TREA. g Long-term CO production represented as the H2:CO ratio, CO FEs, and cell voltages (blue) for coral-Ag/C at −100 mA cm−2 in 3 M TREA.
