Electroreduction of nitrite (NO2-) to ammonia (NH3) provides a sustainable approach to yield NH3 while eliminating NO2- contaminants. In this study, Ni nanoparticles strutted 3D honeycomb-like porous carbon framework (Ni@HPCF) is fabricated as a high-efficiency electrocatalyst for selective reduction of NO2- to NH3. In 0.1 M NaOH with NO2-, such Ni@HPCF electrode obtains a significant NH3 yield of 12.04 mg h-1 mgcat.-1 and a Faradaic efficiency of 95.1%. Furthermore, it exhibits good long-term electrolysis stability.
