Fig. 4: CO2RR electrochemical performance.
From: A chelate to break diffusion limits on Helmholtz plane for CO2 electroreduction to ethanol
FEs of various products and j of C2H5OH and C2+ products under various applied potentials without iR compensation (internal resistance: 0.7 ± 0.2 Ω) over (a) CA Cu, (b) commercial Cu in electrolyte without CA, (c) commercial Cu in electrolyte with 1 mM CA. The error bars correspond to the standard deviation of three independent measurements. d The ratios of FEC2H5OH to FECH4, e FEC2+ to FECH4 under different applied potentials over CA Cu, and commercial Cu in electrolyte without and with 1, 5, 10 mM CA. f Comparison of CA Cu with advanced Cu electrocatalysts for C2H5OH electrosynthesis in terms of FE and j of C2H5OH.
