A “Pre‐Constrained Metal Twins” Strategy to Prepare Efficient Dual‐Metal‐Atom Catalysts for Cooperative Oxygen Electrocatalysis
Abstract
Dual‐metal‐atom‐center catalysts (DACs) are a novel frontier in oxygen electrocatalysis, boasting functional and electronic synergies between contiguous metal centers and higher catalytic activities than single‐atom‐center catalysts. However, the definition and catalytic mechanism of DACs configurations remain unclear. Here, a “pre‐constrained metal twins” strategy is proposed to prepare contiguous FeN 4 and CoN 4 DACs with homogeneous conformations embedded in a N‐doped graphitic carbon (FeCo‐DACs/NC). A programmable phthalocyanines dimer is used as a structural moiety to anchor the bimetallic sites (containing Co and Fe) in a metal–organic framework (MOF) to achieve delocalized dispersion before pyrolysis. The resultant FeCo‐DACs/NC exhibits excellent electrochemical performance in oxygen electrocatalysis and rechargeable Zn–air batteries. Theoretical calculations demonstrate that the synergetic interaction of adjacent metals optimizes the d‐band center position of metal centers and balances the free energy of the *O intermediate, thereby improving the oxygen electrocatalytic activity. This work opens up an avenue for the rational design of DACs with tailored electronic structures and uniform geometric configurations.

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.
