Article Synopsis
- Electrochemical reduction of nitrite to ammonia is an effective method for simultaneously producing ammonia and removing nitrogen-based contaminants, but there is a need for better catalysts.
- This study introduces an efficient electrocatalyst made of Ag nanoarrays supported on NiO nanosheets on carbon cloth, achieving a high ammonia yield of 5,751 μg/h cm in a 0.1 M NaOH and 0.1 M NO environment.
- The research also employs density functional theory calculations to analyze and understand the mechanism behind the reduction of nitrite using this Ag-based catalyst.

Ammonia (NH) plays an important role in agriculture and industry. The industry-scale production mainly depends on the Haber-Bosch process suffering from issues of environment pollution and energy consumption. Electrochemical reduction can degrade nitrite (NO) pollutants in the environment and convert it into more valuable NH.

Electrocatalytic eight-electron nitrate (NO) reduction is a sustainable strategy to degrade NO and convert it into high value-added ammonia (NH) but needs efficient catalysts with high activity and selectivity. Our study shows the use of Ti plate supported cobalt-phosphorus alloy film (Co-P/TP) as a highly active and selective electrocatalyst for ambient NO-to-NH conversion. In 0.
