From: Stabilizing copper sites in coordination polymers toward efficient electrochemical C-C coupling
Faradaic efficiencies (FEs) of all products under different applied potentials over Cu(OH)BTA (a) and Cu(OH)BTA-derived Cu (b) in 1 M KOH electrolyte. c The formation rates of C2+ products and C2H4 under different applied potentials over Cu(OH)BTA and Cu(OH)BTA-derived Cu in 1 M KOH electrolyte. d FEs of all gas products at the full-cell voltage range of 3.0–4.0 V measured in a membrane-electrode assembly (MEA) device. e C2H4 electrosynthesis in the MEA with a geometric electrode area of 4 cm2. The catalyst retains its total current and ethylene FE for 67 h. The error bars for FE uncertainty represent one standard deviation based on three independent samples.
