R. China Ammonia synthesis is the production of ammonia from the combination of hydrogen and nitrogen gases. The great challenge of ammonia synthesis, electrochemical or otherwise, is the requirement to take dinitrogen from the air, and break it in two. It does not occur spontaneously -- at least, not on Earth because of the relatively low temperatures here; it requires a catalyst to commence the reaction, instead. Plasma synthesis of ammonia (NH 3) is a potential and sustainable pathway for nitrogen fixation.In this study, non-thermal plasma (NTP) synthesis of NH 3 was conducted in a packed-bed dielectric barrier discharge (DBD) reactor. Now, an alternative route for ammonia synthesis is proposed from exhaust NO via electrocatalysis.
