In this study, we have focused on the Advance Oxidation Process (AOP) of NH3 a species of odoured inorganic compounds in a plasma-photocatalytic hybrid system and investigated the mechanism for the AOP of NH3. In order to the optimum condition for the oxidation of NH3 with plasma system was carried out reaction at the applied voltage of 5, 7 and 10 kV. Also, the reaction mechanism and catalytic cycle for the AOP of NH3 has been elucidated by in situ FT-IR studies under steady-state conditions. It is found that the optimum condition was at the applied voltage of 10kV and the catalytic activity was better than that loaded vanadium amount of 5mol%. In the plasma only system, the activity of the NH3 oxidation was similar to that in the photocatalytic system. On the other hand, the plasma-photocatalytic hybrid system proved to the conversion of 100% just 30minutes after reaction. Consequently, the plasma-photocatalytic hybrid system could be provided the better effect for NH3 decomposition compared with only photo or plasma systems. |
