Catalyst for purification of exhaust gases. |
摘要 |
<p>A catalyst is comprised of a catalyst carrier (2; 6) and a coat layer (3, 4; 7) containing cerium particles, active alumina particles and a catalyst component of a noble metal; and barium oxide is immobilized on the cerium oxide particles. The catalyst can suppress the growth of crystals of cerium oxide due to the immobilization of the barium oxide thereon, thereby improving heat resistance of the catalyst.</p> |
