摘要 | Partial positive valence Cu (Cuδ+) sites on Cu-based electrocatalysts are important for C-C coupling to form C2+ products; however, maintaining the stability of Cuδ+ remains a challenge. Herein, an ultrastable Cuδ+ (0 2+ Faradaic efficiency (FE) of 78.9% at −0.91 V (vs reversible hydrogen electrode), of which the ethanol FE reaches 52.4% with an ultrahigh partial current density of 1.25 A cm-2, far outperforming state-of-the-art electrocatalysts, corresponding to the ethanol cathodic energy efficiency (CEE) of 27.7%. Spectroscopy and computation results show that introducing boron to optimize the coordination numbers and oxidation states of surface Cu atoms enables enrichment of locally asymmetric *COatop and *CHO intermediates to trigger asymmetric C-C coupling to form ethanol. © 2023 American Chemical Society. |
