Fig. 3: CO reaction order for COER.
From: Unraveling the rate-determining step of C2+ products during electrochemical CO reduction
The current density of C2+ products versus CO partial pressure for interval linear (a) and non-linear (b–e) data fitting as well as their residuals (f). The equations used for fitting (b–e) are the theoretical rate expressions corresponding to different mechanisms (see Supplementary Table 1 for all the fitting parameters). All those data are collected in CO-saturated 0.1 M KOH electrolyte at –1.3 V vs. SHE. Error bars are means ± standard deviation (n = 3 replicates).
