摘要：
A series of single metal oxide catalysts were prepared and their catalytic activities were investigated for simultaneous removal of soot and NO, in an oxygen rich condition. Effects of contact intensity between catalyst and soot as well as simultaneous removal paths for soot and NO, were also studied. Results showed that metal oxide catalysts of Cr, Mn, Co, and Ni exhibited high activities for simultaneous removal of soot and NOx and still had high activities in the loose contact mode between catalyst and soot. Simultaneous removal paths found were that NO2 formation by oxidation of NO promoted soot oxidation and CO, formation by soot oxidation reduced NOx.
