Atomically Dispersed Co2–N6 and Fe–N4 Costructures Boost Oxygen Reduction Reaction in Both Alkaline and Acidic Media
Open accessAbstract
Polynary transition‐metal atom catalysts are promising to supersede platinum (Pt)‐based catalysts for oxygen reduction reaction (ORR). Regulating the local configuration of atomic catalysts is the key to catalyst performance enhancement. Different from the previously reported single‐atom or dual‐atom configurations, a new type of ternary‐atom catalyst, which consists of atomically dispersed, nitrogen‐coordinated Co–Co dimers, and Fe single sites (i.e., Co 2–N 6 and Fe–N 4 structures) that are coanchored on highly graphitized carbon supports is developed. This unique atomic ORR catalyst outperforms the catalysts with only Co 2–N 6 or Fe–N 4 sites in both alkaline and acid conditions. Density functional theory calculations clearly unravels the synergistic effect of the Co 2–N 6 and Fe–N 4 sites, which can induce higher filling degree of Fe–d orbitals and favors the binding capability to *OH intermediates (the rate determining step). This ternary‐atom catalyst may be a promising alternative to Pt to drive the cathodic ORR in zinc–air batteries.

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.
