Fig. 2: Bi and Au/C: NRR vs. NOx reduction.
From: Identification and elimination of false positives in electrochemical nitrogen reduction studies
Comparison of the NH3 formation rates for electrodes modified with a Bi (tested at −0.65 V vs. reversible hydrogen electrode, RHE) and b Au/C (tested at −0.30 V vs. RHE) reported in the literature (entries 97–98 in Supplementary Table 1) and measured in our laboratory in the presence of Ar, N2 and different NOx compounds using 0.5 M K2SO4 aqueous electrolyte solutions (for further details, see ref. 4). All data are presented as an average ± standard deviation calculated for tests with three independent samples of each type.
