Despite the recent developments and progress in understanding the plasma-mediated ammonia synthesis from N2 and H2 there is still much to be done. At the same time, the use of novel hydrogen sources such as seawater is expected to alter these proposed reaction pathways . This work seeks to provide plausible pathway insights into the plasma activation of N2 and sea water vapor for ammonia production. Experimental results of this work indicated that ammonia was not detected from the reaction between N2 and sea water vapor with no catalyst. Therefore, it is worthwhile to mention that a catalyst is needed to provide an active surface for plasma activated N2 species to react with H* species dissociated from H2O vapor. Other researchers also reveal that an active surface is necessary to secure a good ammonia synthesis rate . DBD plasma offers a high degree of excitation (vibrational or electronic) however it observes a low degree of dissociation . Some researchers also indicate the possibility that N2 is not completely dissociated in the plasma environment and the presence of a heterogeneous catalyst could facilitate the dissociation of the plasma-generated species . However, recent experimental-theoretical work from our group shows the importance of N radicals as they are more reactive compared to N vibrational species. And even a minute presence of N radicals can offer a pivotal effect in the synthesis of ammonia from N2 and H2. However, most of the reported mechanisms for ammonia synthesis from N2 and H2 include the formation of plasma-induced vibrationally excited N2() species and the excitation of adsorbed N(ads) on the catalyst surface to react with H2 to form NH3 via either Eley-Rideal (E-R) or Langmuir-Hinshelwood (L-H) . With both the E-R and L-H mechanisms involved in many reactions to form ammonia. Meaning either N radicals or N vibrational species can be disregarded as both play a role in the ammonia synthesis reactions.
