Direct Decomposition of NO over Plasma-Assisted Catalytic System Induced by Microwave Irradiation

다국어 초록 (Multilingual Abstract)

Direct decomposition of NO was carried out over plasma-assisted catalytic system (PACS) having both microwave absorbents for plasma generation and NO decomposition catalysts for the conversion of NO into N_2 and O_2; Co_3O_4 and SiC were used as microwave absorbents and Cu-ZSM-5 was used as a NO decomposition catalyst.
Stable and light blue-colored plasma could be generated successfblly in atmospheric condition over 95 wt% SiC/Cu-ZSM-5 and 25 wt% Co_3O_4/Cu-ZSM-5 PACS-5 by the irradiation of continuous microwave, which showed superior NO decomposition activity.
More than 98% of NO was decomposed into N_2 and O_2 without the formation of N_2O over 25 wt% Co_3O4/Cu-ZSM-5 PACSs at GHSV > 45000 h^-1 and the apparent temperature of 280℃.
