Catalytic reduction of NO with decomposed methanol on alumina-supported Mn-Ce catalysts

► Mn-Ce/Al2O3 performes good activity in integrated devices of SCR of NOx with CO from decomposed methanol at 723 K. ► The activity was related to the formation of mixed Mn3+/Ce4+ and Ce3+/Mn4+ sites. ► The interaction between the active species depends on the composition of bicomponent materials.
