Abstract in different language: The catalytic activity of a series of La-Fe catalysts supported on activated carbon was studied for selective catalytic reduction of NO by CO. Increasing the amount of La in the catalyst structure causes an increase in the Fe2+/Fe3+ ratio. The results showed that by increasing the La amount in catalysts, the catalytic activity of the AC-supported catalysts was enhanced because of the synergistic interactions between surface oxygen vacancies and Fe2+ species in the AC-supported catalysts. Due to the high catalytic performance of MnOx, the NOx conversion of Mn@La3-Fe1/AC catalyst was improved to 92.67% at the absence of oxygen at 400 °C. The Mn promoted La3- Fe1/AC catalyst showed the highest NOx conversion of 93.8% at 400 °C in the presence of 10% excess oxygen. Compared with other prepared catalysts, the Mn@La3-Fe1/CNT catalyst showed the highest activity due to the higher Fe2+/Fe3+, which confirmed by XPS analysis. The double exchange behavior of Mn3+ and Mn4+ can increase the number of SOV and increase catalytic redox properties.
