a Atomic fractions of Cu, C, and O for G-CuNW, AA-CuNW, and cAA-CuNW. C 1s XPS spectra of (b) G-CuNW and (c) cAA-CuNW. d FT-IR spectra of p-CuNW, G-CuNW, AA-CuNW, and cAA-CuNW. e XRD patterns of p-CuNW, G-CuNW, AA-CuNW, and cAA-CuNW. f Conceptual schematic of the surface components of Nafion ionomer-coated cAA-CuNWs for enhanced CO2-to-*CO conversion and *CO dimerization during the CO2RR. g Comparison of the amount of DHA extracted from AA-CuNW and cAA-CuNW with and without the Nafion ionomer coating. The extracted DHA concentration was analyzed by HPLC.
