Cu-Fe Dual Sites for Superior Neutral Ammonia Electrosynthesis from Nitrate.
Angew Chem Int Ed Engl
July 2024
The electrochemical nitrate reduction reaction (NORR) is able to convert nitrate (NO ) into reusable ammonia (NH), offering a green treatment and resource utilization strategy of nitrate wastewater and ammonia synthesis. The conversion of NO to NH undergoes water dissociation to generate active hydrogen atoms and nitrogen-containing intermediates hydrogenation tandemly. The two relay processes compete for the same active sites, especially under pH-neutral condition, resulting in the suboptimal efficiency and selectivity in the electrosynthesis of NH from NO .

Herein, we first report the synthesis of nitrogen-doped BiOCl atomic layers to directly split carbon-sequestrated natural seawater (Yellow Sea, China) into stoichiometric CO (92.8 μmol h ) and HClO (83.

- The study investigates how controlling reactive oxygen species (ROS) is crucial for using photocatalysis to remove pollutants, specifically focusing on BiOBr nanosheets.
- It highlights that modifying the surface with boron reduces excitonic effects, leading to enhanced charge carrier generation and the creation of more effective reactive species for pollutant degradation.
- This approach improves the conversion of toxic nitrogen oxides (NO) into safer nitrates, demonstrating a practical method for optimizing photocatalytic materials for cleaner indoor air under visible light.
