Toward the realization of carbon neutrality, a detailed understanding of plasma reaction fields involving N_xH_y species is essential for the interconversion of hydrogen and ammonia, which are promising next-generation energy carriers, as well as for the controlled synthesis of short-lived N_xH_y species. In this study, focusing on N₂/NH₃ plasma reaction fields, experimental measurements of various N_xH_y species and improvements to reaction simulations were conducted to estimate radical reaction rates, with the aim of establishing technologies for interconversion and selective conversion to useful N_xH_y species. In this presentation, the detailed reaction mechanisms of N_xH_y species will be discussed.
