Abstract
Correction for ‘Electrochemical nitrogen fixation and utilization: theories, advanced catalyst materials and system design’ by Wenhan Guo et al., Chem. Soc. Rev., 2019, 48, 5658–5716, https://doi.org/10.1039/C9CS00159J.
The authors regret that the pKa of hydrazine was incorrectly given in the original article. The correct value should be 7.93. This means that eqn (8) and (9) and Fig. 3 were incorrect. The correct versions are shown below. This also applies to the sentence beginning “For hydrazine, the case is similar…”, where the boundary should be given as 7.93.
| N2(g) + 5H+ + 4e− ⇌ N2H5+(aq.) (pH < 7.93) E0 = −0.214 V vs. RHE at pH = 0 | (8) |
| N2(g) + 4H2O(l) + 4e− ⇌ N2H4(aq.) + 4OH−(aq.) (pH ≥ 7.93) E0 = −0.332 V vs. RHE | (9) |
