摘      要：Excellent catalysts with low-temperature activity and relatively wide temperature window for selective catalytic reduction of NO with ammonia(NH_(3)-SCR) are highly demanded in view of the practical treatment of ***,we have designed a highly active VOx-MnOx/CeO_(2) material based on the intrinsic requirement of SCR reaction for catalyst,namely redox sites and surface acid *** vanadium oxide and manganese oxide are highly dispersed over the ceria mesosphere via simple incipient wetness *** loading of manganese could introduce acid sites and enhance the redox property remarkably,while the loading of vanadium increases acid sites and weakens redox *** tentatively controlling the appropriate loading ratio of the two components,the optimal catalyst achieves a balance between redox property and surface *** work shed light on the development of new SCR catalyst with superior low temperature activity,wide work temperature window and good hydrothermal stability.
