摘要 Ceria is widely used as a promoter in "three-way catalysts" (TWC). The promotion effect of ceria was originally supposed to be in the structural aspects and chemical ones. Precious metals are widely used for exhaust gas emission control. However, because the high cost of precious metals and their sensitivity to sulfur poisoning, attention has been given to nonprecious metal catalysts such as copper oxide.
