Near-Unity Nitrate to Ammonia conversion via reactant enrichment at the solid-liquid interface

Nature Communications
Electroreduction of nitrate (NO3 ‒) to ammonia (NH3) is a promising approach for addressing energy challenges. However, the activity is limited by NO3 ‒ mass transfer, particularly at reduction potential, where an abundance of electrons on the cathode ...

Sustainable conversion of alkaline nitrate to ammonia at activities greater than 2 A cm−2

Nature Communications
Nitrate (NO3 ‒) pollution poses significant threats to water quality and global nitrogen cycles. Alkaline electrocatalytic NO3 ‒ reduction reaction (NO3RR) emerges as an attractive route for enabling NO3 ‒ removal and sustainable ammonia (NH3) synthesis.
