Abstract

Electrochemical nitrite (NO₂^-) reduction to ammonia (NH₃) can not only remove harmful NO₂^- in wastewater, but also produce valuable NH₃. Herein, a CoFe nanoalloy encapsulated in nitrogen-doped carbon (CoFe-NC) electrocatalyst was fabricated for nitrite reduction, which achieved a high NH₃ Faraday efficiency of 94.5%, and a large NH₃ yield of 4050.6 μg h^-1 cm^-2 in a neutral electrolyte.
