Corrigendum: A Versatile In Situ Electron Paramagnetic Resonance Spectroelectrochemical Approach for Electrocatalyst Research

Abstract

The authors have identified some errors in their manuscript. On page 4583, the hyperfine couplings for the methyl viologen (MV) radical cation are stated as shown in bold: In situ electrolysis experiments were performed as described in §1. The employed electrodes were bare ITO, Ag/ITO, and the NiO/ITO. Potentials in the kinetic region of the corresponding CVs were applied. Figure 7 displays the spectra that were obtained for BQ and MV reductions. The EPR spectra were simulated using the EasySpin-5.1.11 module running in Matlab.[60] The following isotropic g and hyperfine values were used for the simulation of the spectra of the BQ radical anion: gBQ=2.0050 with AH=6.75 (4), while for the MV radical cation gMV=2.0024, AN=11.85 (2), AH=11.18 (6), AH=3.40 (4), AH=11.18 (4). These are in accordance with the literature values.[18,61] This should be changed to: In situ electrolysis experiments were performed as described in §1.

These are in accordance with the literature values.[18,61] The authors confirm that these changes do not affect the results or conclusions and they apologize for the errors and for any inconvenience caused.
