Abstract
Production of ammonia (NH3) from flue gas (i.e., NO) via the electrocatalytic route has been considered a promising approach for rejuvenating the environment over the conventional methods. MOF-derived zero-valent nickel nanoparticles wrapped with nitrogen-doped carbon nanostructures (NiNC) were successfully grown on a carbon fiber (CF). The NiNC@CF catalyst delivered an NH3 yield rate of 94 mu mol h(-1) cm(-2) with significantly high faradaic efficiency (87%) at -0.5 V vs. RHE. Coupling with an OER catalyst in a full cell system produces 88 mu mol h(-1) cm(-2) of NH3 with long-term stability.
