In terms of nitrogen fixation, such nitrogen oxide can be a useful platform for other chemicals production. A possible concept to make a full use of downstream products from ammonia synthesis is the addition of a membrane DBD plasma reactor to separate produced N2O for other chemical synthesis i.e., HNO3 with air while the formed ammonia can be liquefied. This product separation strategy in a DBD reactor has been explored by our group for the N2/H2 plasma ammonia synthesis . Another solution is to recycle the formed NOx to the reactor for ammonia synthesis . A possible concern is whether a desalination step is necessary to translate seawater to purer water prior to entering to the DBD reactor for ammonia synthesis reaction. This is originated from an apprehension that seawater possibly causes oxidation of the electrode of the DBD reactor. Nevertheless, even though either pure water or air was used, the inner electrode of the DBD reactor also deals with oxidative issues under long-term cycling reactions. Such phenomenon requires a thoughtful study to assess the effects of oxygen- Insights on the plasma ammonia pathway from sea water vapor and N2 plasma activation.
