Ambient N2 fixation to NH3 at ambient conditions: Using Nb2O5 nanofiber as a high-performance electrocatalyst
Abstract
Abstract Electrochemical reduction has emerged as an environmentally-benign and sustainable approach alternative to the Haber–Bosch process for artificial N2 fixation at ambient conditions, while the challenge associated with N2 activation underlines the demand of efficient electrocatalysts for the N2 reduction reaction (NRR). In this work, Nb2O5 nanofiber is experimentally proved to act as a non-noble-metal NRR electrocatalyst for N2 conversion to NH3 with high activity and selectivity. When tested in 0.1 M HCl, such Nb2O5 nanofiber achieves a high average NH3 yield (43.6 µg h−1 mg−1cat.) and a high Faradaic efficiency (9.26%) at − 0.55 V vs. reversible hydrogen electrode, rivaling the performances of most reported aqueous-based NRR electrocatalysts under ambient conditions and even comparable with those under high temperature and pressure. Notably, it also shows high stability during electrolysis and recycling test. The catalytic mechanism of NRR on Nb2O5 (181) surface is further discussed by density functional theory calculations.

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.
