| titleOfInvention | Exhaust gas purification catalyst |
| abstract | An object of the present invention is to provide an inexpensive catalyst without using an expensive precious metal and to exhibit sufficient oxidation activity even if it does not reach Pt. A composite oxide comprising a solid solution of ceria, a metal or oxide of at least one element selected from Zr and Fe, and a metal or oxide of at least one element selected from Ag and Pr. including. Compared to conventional catalysts that support inexpensive transition metals such as Ag or Fe, the oxidation activity of CO and HC is remarkably high, so emissions at low temperatures such as at startup are improved. In addition, by arranging upstream of the three-way catalyst, the warm-up property of the three-way catalyst is improved, and the emission in a low temperature region such as at the time of starting is further improved. And since an expensive noble metal such as Pt is not used, it becomes an inexpensive catalyst. [Selection] Figure 2 |
