Ambient electrochemical synthesis of ammonia from nitrogen and water catalyzed by flower-like gold microstructures
Abstract
Abstract Electrochemical nitrogen reduction to ammonia is proposed as a promising alternative to the Haber–Bosch process because it can be driven by renewable electricity at ambient conditions. Currently, the development of such a process is hampered by the lack of efficient electrocatalysts for the nitrogen reduction reaction (NRR). Herein, we report a super‐rapid approach for the synthesis of flower‐like Au microstructures (Au flowers) within 5 s. The obtained Au structures are assembled by staggered nanoplates as building blocks, which provide abundant electrocatalytically active sites for the NRR. The Au flowers achieve a high performance (NH3 yield: 25.57 μg h−1 mgcat.−1; faradaic efficiency: 6.05 %), 100 % selectivity (no N2H4 production), and long‐term durability toward the electrochemical ammonia production. The work is highly valuable for the rapid synthesis of active catalysts for the NRR.

Both yield metrics are significantly below the minimum yield threshold for practical eNRR, set at 100 nmol s−1 cm−2, assuming an electrocatalyst loading of about 1 mg cm−2.

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.
