Reactivity Descriptors for the Activity of Molecular MN4 Catalysts for the Oxygen Reduction Reaction
Open accessAbstract
Similarities are established between well‐known reactivity descriptors of metal electrodes for their activity in the oxygen reduction reaction (ORR) and the reactivity of molecular catalysts, in particular macrocyclic MN4 metal complexes confined to electrode surfaces. We show that there is a correlation between the M III/M II redox potential of MN4 chelates and the M‐O 2 binding energies. Specifically, the binding energy of O 2 (and other O species) follows the M III‐OH/M II redox transition for MnN4 and FeN4 chelates. The ORR volcano plot for MN4 catalysts is similar to that for metal catalysts: catalysts on the weak binding side (mostly CoN4 chelates) yield mainly H 2 O 2 as the product, with an ORR onset potential independent of the pH value on the NHE scale (and therefore pH‐dependent on the RHE scale); catalysts on the stronger binding side yield H 2 O as the product with the expected pH‐dependence on the NHE scale. The suggested descriptors also apply to heat‐treated pyrolyzed MN4 catalysts.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
