A Cu2S/NiOOH Heterojunction Enables Highly Selective Ammonia-to-Nitrite Electrooxidation at Industrially Relevant Current Densities.
Electrocatalytic ammonia oxidation reaction (AOR) offers a green route to nitrite (NO2 -) synthesis while coupling hydrogen evolution reaction. However, maintaining NO2 - selectivity at high current density remains challenging due to the narrow thermodynamic windows for NO2 - and nitrate (NO3 -) formation and competiti...
