Abstract
Electrochemical reduction of nitrate, which is a widespread pollutant, offers an alternate approach for the ammonia synthesis. Developing a stable catalyst that can selectively reduce nitrate to ammonia in a neutral medium is considered in this study. An active catalyst based on iron oxide supported on boron carbon nitride (γ-Fe2O3/BCN) is developed. The catalyst shows a Faradaic efficiency of 95% (at −0.59 V vs RHE) and yield rate of 7570 μg h–1 mgcat–1 (at −0.64 V vs RHE) of ammonia. The γ-Fe2O3/BCN catalyst also exhibits long-term stability in cyclic tests. The computational studies reveal that the charge transfer between γ-Fe2O3 and BCN in γ-Fe2O3/BCN has a critical role in enhancing the catalytic activity as compared to γ-Fe2O3 and BCN.
