The comparison of Cu nanocubes and 25 nm spherical Cu nanoparticles when used for 10-h tests of a CO2RR at −1.1 VRHE (iR-corrected) in 0.1 M KHCO3 (Table S1, entries 1 and 31) and b CORR test at −0.37 VRHE (iR-corrected) in 1 M KOH (Table S1, entries 36 and 40). Liquid product distributions of the CORR experiments as a function of time for c Cu nanocubes and d 25 nm spherical Cu nanoparticles. The error bars show the standard error of three independent measurements. Insets show ex-situ TEM bright field images of the corresponding sample in each case before and after the CORR experiments.
