Abstract

Compositional and structural engineering of metal‐metalloid materials can boost their electrocatalytic performance. Herein, a highly efficient and stable electrocatalytic system for the oxygen reduction reaction is obtained by creating heterointerfaces between N‐doped carbon and cobalt boride nanosheets. Furthermore, a detailed investigation on the effect of annealing temperature as well as the amount of carbon and nitrogen sources is conducted to tune their performance. The best electrocatalyst among the prepared materials is found to have an onset potential of 1.05 V and half‐wave potential of 0.94 V, which are 40 and 72 mV positive in comparison to commercial Pt/C, respectively. Finally, a zinc–air battery is also assembled using the catalyst.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Metal-heteroatom alloying is a useful pathway to improve catalytic performance by redistributing electron density and optimizing adsorption energy of reactant species.

    “metal-heteroatom alloying is regarded as one of the most useful pathways to further improve the catalytic performance by redistributing the electron density of catalysts and optimizing the adsorption energy of the reactant species on the catalyst surface30–34.”

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.
