文摘

•: Cu/Ce_0.5Pr_0.5O_2-δ catalysts are active in soot oxidation.
•: Soot combustion activity is enhanced in the presence of Cu/Ce_0.5Pr_0.5O_2-δ and Ce_0.5Pr_0.5O_2-δ.
•: Reduction of Ce and Pr in Ce_0.5Pr_0.5O_2-δ is promoted to lower temperatures by copper.
•: Cu supported on Ce_0.5Pr_0.5O_2-δ particles promotes the NO_x-assisted mechanism.
•: Oxidation of soot over Ce_0.5Pr_0.5O_2-δ occurs through the active oxygen mechanism.
