The Marriage of the FeN4 Moiety and MXene Boosts Oxygen Reduction Catalysis: Fe 3d Electron Delocalization Matters
Abstract
Iron–nitrogen–carbon (Fe–N–C) is hitherto considered as one of the most satisfactory alternatives to platinum for the oxygen reduction reaction (ORR). Major efforts currently are devoted to the identification and maximization of carbon‐enclosed FeN 4 moieties, which act as catalytically active centers. However, fine‐tuning of their intrinsic ORR activity remains a huge challenge. Herein, a twofold activity improvement of pristine Fe–N–C through introducing Ti 3 C 2 Tx MXene as a support is realized. A series of spectroscopy and magnetic measurements reveal that the marriage of FeN 4 moiety and MXene can induce remarkable Fe 3d electron delocalization and spin‐state transition of Fe(II) ions. The lower local electron density and higher spin state of the Fe(II) centers greatly favor the Fe electron transfer, and lead to an easier oxygen adsorption and reduction on active FeN 4 sites, and thus an enhanced ORR activity. The optimized catalyst shows a two‐ and fivefold higher specific ORR activity than those of pristine catalyst and Pt/C, respectively, even exceeding most Fe–N–C catalysts ever reported. This work opens up a new pathway in the rational design of Fe–N–C catalysts, and reflects the critical influence of Fe 3d electron states in FeN 4 moiety supported on MXene in ORR catalysis.

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.
