Defect Engineering Strategies for Nitrogen Reduction Reactions under Ambient Conditions

Yan, Dafeng, Li, Hao, Chen, Chen, Zou, Yuqin, Wang, Shuangyin·2019·Small Methods

Abstract

The production of ammonia from N 2 molecules under ambient conditions [electro (photo) chemical reduction] is one of the most attractive topics in the energy‐related field due to its unique advantages and great potentials. Recently, various catalysts have been explored to show certain activities in nitrogen reduction reactions (NRRs) at room temperature and atmospheric pressure. To further improve the catalytic activity and increase the selectivity, the catalysts should be rationally designed to introduce extra active sites for the N 2 molecule adsorption and activation. This review summarizes recent progress of the defect engineering strategies to design highly efficient electrochemical or photocatalytic NRR nanocatalysts. The defect sites would serve as the active center for the NRR and further enhance its intrinsic performance. The defect engineering strategies are summarized in different categories, including vacancies (oxygen, nitrogen, and sulfur vacancies), doping (metal doping and nonmetal doping), amorphous phases (amorphous noble metal and amorphous transition metal), size effects, and structure effects. In addition, the different ammonia determination methods are summarized and compared in order to obtain more credible and veritable NRR performance results.

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.
