Single‐Site Gold Catalysts on Hierarchical N‐Doped Porous Noble Carbon for Enhanced Electrochemical Reduction of Nitrogen
Open accessAbstract
Electrocatalytic reduction of nitrogen (N 2) at ambient conditions is an alternative strategy to produce ammonia (NH 3) to complement the commonly applied Haber–Bosch process. However, the achievement of high Faradaic efficiencies and high NH 3 yield is still challenging. Here, Au single sites stabilized on N‐doped porous and highly oxidizing (“noble”) carbon catalysts showing excellent performance in N 2 electroreduction are reported. At a potential of −0.2 V versus reversible hydrogen electrode, a stable NH 3 yield of 2.32 µg h−1 cm−2 is produced at a Faradaic efficiency of 12.3%. Besides, there is no notable fluctuation of Faradaic efficiency and NH 3 yield in six‐cycle test, which indicates good stability. This work opens up new insights to improve N 2 fixation performance by introducing catalytically active single sites into noble carbon materials for N 2 electroreduction.

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.
