英文摘要	Catalytic performances of a series Ce/Zr oxides(CexZr1-xO2)for soot combustion were investigated. The catalytic activities for soot combustion were affected by both the Ce/Zr ratio and the oxygen storage capability of Ce/Zr oxides. O-2-TPD and TG-DTA results indicate that CexZr1-xO2, can release its lattice oxygen continuously and promote soot combustion even no oxygen occurs in the reaction atmosphere. Among these Ce/Zr oxides, Ce0.5Zr0.5O2 has the best catalytic activity, and the ignition temperature of soot combustion was about 410 degreesC, which is close to the practical exhaust temperature of the diesel engine.
