Figure 3. Electrochemical CO2RR performance of
commercial Cu NP, CuO NS, Cu-30, and Cu-100. (a)
LSV curves of Cu-30 in the
CO2- and Ar- saturated 0.1 M KHCO3electrolyte after 1hr electrolysis. (b) Overall Faradaic efficiencies at
a potential of −1.1 V vs. RHE, partial faradaic efficiency (FE) for (c)
C2H4 and (d) C2+products, (e) partial current density of total C2+products.
