In this study, we propose a novel method for ammonia synthesis under ambient temperature and pressure by integrating atmospheric-pressure plasma with in-situ separation using a membrane. By selectively and rapidly removing the generated ammonia from the reaction zone, the method suppresses its reverse decomposition and thereby enhances the reaction efficiency. Experimental results demonstrated that the introduction of the separation membrane significantly improved both the ammonia production rate and its concentration in the recovered gas, with no observable degradation in membrane performance. This approach represents a promising technology for advancing the electrification of chemical processes.
