Abstract
The metal oxide catalyst was prepared by loading MnOx and FeOx on carbon nano-tubes (CNTs) with impregnation method. Then the catalyst was characterized by BET and XPS, and the effect of adding FeOx on MnOx/CNTs catalyst at the low-temperature selective catalytic reduction of NO with NH 3 was investigated. The results showed that the active components were loaded suc-cessfully and easily on the carriers by impregnation. The Mn-Fe/CNTs catalyst was chose 10% Fe(NO 3 ) 3 solution to impregnate Mn-Fe/CNTs. The species of active components loaded on the catalyst were Fe 2 O 3 . The different concentration of impregnant solution played an important role for NO conversion in SCR with NH 3 . With the increase of the concentration of impregnant solution, the NO conversion of catalysts was increasing initially then decreasing.
