Ultralow overpotential nitrate reduction to ammonia via a three-step relay mechanism
Open accessAbstract
Ammonia plays a substantial role in agriculture and the next generation of carbon-free energy supply. Electrocatalytic nitrate reduction to NH_3 is attractive for nitrate removal and NH_3 production under ambient conditions. However, the energy efficiency is limited by the high reaction overpotential. Here we propose a three-step relay mechanism composed of a spontaneous redox reaction, electrochemical reduction and electrocatalytic reduction to overcome this issue. Ru_ x Co_ y alloys were designed and adopted as model catalysts. Ru_15Co_85 exhibits an onset potential of +0.4 V versus reversible hydrogen electrode, and an energy efficiency of 42 ± 2%. The high performance results in a low production cost of US$0.49 ± 0.02 per kilogram of ammonia. The high nitrate reduction performances on Ru_15Fe_85 and Ru_15Ni_85 also highlight the promising potential of the relay mechanism. Electrocatalytic nitrate reduction represents an opportunity to generate ammonia under ambient conditions, yet the efficiency has been limited by the large overpotential required. Here, a Ru–Co alloy demonstrates a three-step relay mechanism involving a spontaneous redox step that reduces the overpotential for the process.

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.
