| titleOfInvention | Exhaust gas purification catalyst manufacturing method |
| abstract | (57) [Summary] [Purpose] To more efficiently purify NOx in exhaust gas in excess of oxygen and improve the NOx purification performance after endurance. [Structure / Function] A rare earth element (La or the like), a noble metal (Pt or the like), and an alkaline earth metal (Ba or the like) are loaded in this order on a porous carrier containing alumina on the surface. It is considered that since the alumina and the rare earth element react with each other and the surface state of the carrier is modified, the alkaline earth metal is adsorbed in a highly dispersed state and the alkaline earth metal having a small particle size is carried. |
