Abstract

Electrocatalysts for both the oxygen reduction and evolution reactions (ORR and OER) are vital for the performances of rechargeable metal–air batteries. Herein, we report an advanced bifunctional oxygen electrocatalyst consisting of porous metallic nickel‐iron nitride (Ni 3 FeN) supporting ordered Fe 3 Pt intermetallic nanoalloy. In this hybrid catalyst, the bimetallic nitride Ni 3 FeN mainly contributes to the high activity for the OER while the ordered Fe 3 Pt nanoalloy contributes to the excellent activity for the ORR. Robust Ni 3 FeN‐supported Fe 3 Pt catalysts show superior catalytic performance to the state‐of‐the‐art ORR catalyst (Pt/C) and OER catalyst (Ir/C). The Fe 3 Pt/Ni 3 FeN bifunctional catalyst enables Zn–air batteries to achieve a long‐term cycling performance of over 480 h at 10 mA cm−2 with high efficiency. The extraordinarily high performance of the Fe 3 Pt/Ni 3 FeN bifunctional catalyst makes it a very promising air cathode in alkaline electrolyte.

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.
