High-Density Planar-like Fe2N6 Structure Catalyzes Efficient Oxygen Reduction
Open accessAbstract
Summary Metal-nitrogen-carbon materials have been demonstrated as the most promising non-noble metal catalyst for proton-exchange membrane fuel cells (PEMFCs) but are still limited by the sluggish kinetics and durability of metal-nitrogen active sites. Here, we unravel a planar-like Fe2N6 active site as a highly efficient oxygen reduction catalyst for PEMFCs. Our developed planar-like Fe2N6 structure behaves as a distinguished catalytic mechanism for oxygen reduction, which brings synergic advantages of accelerated catalytic kinetics and highly suppressed side reaction, successfully promoting its catalytic activity and stability. As expected, the planar-like Fe2N6 structure with high density exhibits over 700% increase in mass activity than traditional isolated iron-nitrogen sites. Moreover, a PEMFC built with this catalyst also achieves a large peak power density of 845 mW cm−2, representing a critical breakthrough for practical application of metal-nitrogen-carbon materials in PEMFC systems. Our findings will provide a new avenue toward designing highly active metal-nitrogen sites for heterogeneous 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.
