Electrochemical activation of dinitrogen (N) is notoriously challenging, typically yielding very low ammonia (NH) production rates. In this study, we present a continuous flow plasma-electrochemical reactor system for the direct conversion of nitrogen from air into ammonia. In our system, nitrogen molecules are first converted into a mixture of NO species in the plasma reactor, which are then fed into an electrochemical reactor.

Article Synopsis
- * NaK liquid metal alloy anodes have been proposed to avoid dendrite formation, but our study shows they still develop an unstable SEI and have cycling failures after 100 cycles, with a notable sodium accumulation on their surface.
- * Adding a 10 wt % fluoroethylene carbonate to the electrolyte helps improve performance, allowing for up to 800 cycles at 1C, but some potassium dissolution into the electrolyte still occurs, highlighting the need for improved SEI designs on NaK anodes.
