Abstract
To provide an oxidation catalyst capable of burning PM of diesel engine exhausts gas at a low temperature, and hardly subjected to poisoning due to sulfur oxide. A composite oxide contains Ce, Bi, and M (wherein M is one or more elements selected from Mg, Ca, Sr, and Ba) and oxygen, and is manufactured, with a molar ratio of Ce, Bi, M expressed by Ce:Bi:M=(1−x−y):x:y, satisfying 0<x≦0.4, and 0<y≦0.4. This composite oxide is suitable as a PM combustion catalyst, and is hardly subjected to poisoning due to sulfur oxide.
