The Non-Thermal Plasma-Assisted Catalytic Conversion of NO under Low-Temperature

Mn-Fe catalyst was prepared by the coprecipitation method. The Mn and Fe molar ratio of this catalyst contained amorphous iron-manganese oxides was 1. The process of Non-thermal plasma-assisted catalytic oxidation of NO under low-temperature was studied. The effect of factors such as space velocity, reaction temperature and composition of mixed gas on NO removal were also investigated. The results showed that over this catalyst, NO oxidation efficiency reached 60% at 100°C and 80% at 150°C And the conversion could reach 78% with the Non-thermal plasma -assisting at 100°C. In addition, the content of nitric acid ion in distilled water was discussed.
