(A) NMR spectrum of acetate (δ = 1.83 ppm) with DMSO (δ = 2.5 ppm) as the internal standard. (B) Efficiency of acetate formation as a function of the atom ratios of Cu and Ag in (Cu)m,(Ag)n/polymer/GCE in CO2-saturated 0.5 M KHCO3, −1.53 V vs. RHE after 3,600 s, 0 °C. (C) Product distribution with (solid) without (empty) 8 ppm BTA on (Cu)2, (Ag)3|80-layer-poly[Fe(vbpy)3](PF6)2|GCE electrode, condition as above. (D) As above, influence of the applied potential on acetate production for a (Cu)2,(Ag)3/polymer/GCE electrode.
