| 摘要 |
The present invention provides a metal composite oxide catalyst for exhaust gas purification, which is represented by formula (I). M1/M2FexMn1-xO3 (I) (In the formula, M1 represents a noble metal selected from the group consisting of Pd, Rh and Pt; M2 represents a rare earth element selected from the group consisting of Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y; and x represents a number of 0.2-1.0. In this connection, M2FexMn1-xO3 represents a metal composite oxide carrier, and M1 is supported by the carrier.) |
