Recent Advance in Heterogenous Electrocatalysts for Highly Selective Nitrite Reduction to Ammonia Under Ambient Condition

Industrial ammonia production mainly relies on the conventional Haber–Bosch process accompanied by high energy consumption and plentiful carbon dioxide emissions, which triggered recent interest to explore more energy‐efficient environmentally benign alternatives. Very recently, electrochemical nitrite reduction in an aqueous medium promises new opportunities for advanced, energy‐efficient, sustainable at ambient conditions. The formation rate Faradic efficiency are strongly associated with adopted electrocatalysts; therefore, striving high‐efficient electrocatalysts is key via reaction. Herein, a critical overview of advances reaction presented, highlighting latest innovative heterogenous including noble metal catalysts, transition‐metal‐based their compounds. Meanwhile, possible pathway electroreduction ammonia, detection, catalytic activity descriptor briefly summarized. Finally, perspective research challenges that convert outlined, increasing contributions route realizing neutral footprint.
