Effect of Addition of Ce on the Catalytic Activity of Fe-Mn-O Catalyst for SCR of NOX with NH3

Fe-Mn oxide and Ce-doped Fe-Mn oxide nanosized particles were studied on the structural and catalytic activities for SCR. The catalysts were characterized by TEM, TPR and BET study. Analysis data show that the addition of Ce improves the reduction performance of Fe-Mn species. It was found that the Ce promoted samples exhibited much better activities for SCR of nitric oxide with ammonia because of the promotion of the structural and redox properties.
