Enabling Effective Electrocatalytic N2 Conversion to NH3 by the TiO2 Nanosheets Array under Ambient Conditions
Abstract
NH 3 serves as an attractive hydrogen storage medium and a renewable energy sector for a sustainable future. Electrochemical reduction is a feasible ambient reaction to convert N 2 to NH 3, while it needs efficient electrocatalysts for the N 2 reduction reaction (NRR) to meet the challenge associated with N 2 activation. In this Letter, we report on our recent experimental finding that the TiO 2 nanosheets array on the Ti plate (TiO 2 /Ti) is effective for electrochemical N 2 conversion to NH 3 at ambient conditions. When tested in 0.1 M Na 2 SO 4, such TiO 2 /Ti attains a high NH 3 yield of 9.16 × 10 –11 mol s –1 ·cm –2 with corresponding Faradaic efficiency of 2.50% at −0.7 V vs reversible hydrogen electrode, outperforming most reported aqueous-based NRR electrocatalysts. It also shows excellent selectivity for NH 3 formation with high electrochemical stability. The superior NRR activity is due to the enhanced adsorption and activation of N 2 by oxygen vacancies in situ generated during electrochemical tests.

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.
