Direct electrosynthesis of 52% concentrated CO on silver’s twin boundary

Abstract: The gaseous product concentration in direct electrochemical CO2 reduction is usually hurdled by the electrode’s Faradaic efficiency, current density, and inevitable mixing with the unreacted CO2. A concentrated gaseous product with high purity will greatly lower the barrier for large-scale CO2 fixation and follow-up industrial usage. Here, we developed a pneumatic trough setup to collect the CO2 reduction product from a precisely engineered nanotwinned electrocatalyst, without using ion-exchange membrane. The … Show more

“…For IW-Ag, the values are 78.81 μm –1 and 41.87% (Figures S8–S10), and for BW-Ag, the values are 57.18 μm –1 and 31.65% (Figures S11–S13). These results indicate that liquid nitrogen can increase the SFD significantly, and the SFD value in LN-Ag is much higher than what was reported in the literature ,,− (Table S2). In addition, the XPS and XRD patterns show that LN-Ag, IW-Ag, and BW-Ag only contain a pure silver phase (Figures g–h), and ablation media did not change the phase constitution of the products.…”
