Abstract

Electrohydrogenation of N 2 to NH 3 is emerging as an environmentally benign strategy to tackle the issues associated with the energy-intensive, CO 2 -emitting Haber–Bosch process. However, the method is severely challenged by N 2 activation and needs efficient N 2 reduction reaction (NRR) catalysts. Here, we report that multishelled hollow Cr 2 O 3 microspheres (MHCMs), which are synthesized by a facile synthetic route, can serve as efficient and selective non-noble metal electrocatalysts for NRR. In 0.1 M Na 2 SO 4 solution, the MHCMs achieve a high Faradaic efficiency (6.78%) and a large NH 3 yield (25.3 μg h –1 mg cat –1 ) at −0.9 V vs reversible hydrogen electrode. The MHCMs also exhibit high stability during the reaction. Density functional theory calculations suggest that NRR over MHCMs occurs via both distal associative and partially alternative routes.

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.
