Selective catalytic reduction of no over metal oxide or noble metal-doped In_2O_3/Al_2O_3 catalysts by propene in the presence of oxygen

摘要

The activities of metal oxide CuO,SnO_2,CoO,Ag_2O,ZnO or noble metal Pt,Pd,Rh-doped In_2O_3/Al_2O_3 catalysts for selective catalytic reduction of NO by propene were investigated.The temperature windows for NO reduction over noble metal-doped In_2O_3/Al_2O_3 catalysts were shifted and broadened slightly compared with single component catalysts.
