What is A Robust Metal-free Electrocatalyst for Nitrate Reduction Reaction to Synthesize Ammonia about?
Electro-synthesis of ammonia at ambient environment is a promising alternative of the industrial Haber-Bosch process operated under critical conditions. In this work, we have systematically investigated the electro-reduction of nitrate (NO 3 À RR) to ammonia catalyzed by fluorine doped carbon (FC) synthesized from the pyrolysis of the discarded cigarette filter saturated with polytetrafluoroethylene (PTFE) solution. FC electrocatalyst shows an exceptional NO 3 À RR catalytic performance with Faradaic efficiency of 20% associated with ammonia production rate of 23.8 mmol h À1 g cat ## À1 , 2 and 4-fold better than bare C electrocatalyst. Furthermore, a stable NO 3 À RR activity is also achieved for FC electrocatalyst. Density functional theory (DFT) results suggest that F dopants efficiently reduce the energy barriers of NO 3 À hydrogenation and suppress the competitive hydrogen evolution reaction (HER). This observation will be beneficial for constructing a high-performance metal-free electrocatalyst to electro-synthesize ammonia from NO 3 À RR.
