Catalyst Composition |
| 摘要 |
An object of the present invention is to provide a catalyst composition containing a perovskite-type composite oxide which exhibits a satisfactory catalytic performance over a long time even in a high temperature atmosphere and has a stable quality in which Rh and/or Pt dissolves to form a solid solution at a high rate. To achieve the object described above, in the present invention the catalyst composition is prepared to comprise an Rh-containing perovskite-type composite oxide represented by the following general formula (I) and/or a Pt-containing perovskite-type composite oxide represented by the following general formula (II) and a thermostable oxide optionally containing a noble metal. <?in-line-formulae description="In-line Formulae" end="lead"?>A1xA2wB11-(y+z)B2yRhzO3±delta (I)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>A3rA4sB31-(t+u)B4tPtuO3±delta' (II)<?in-line-formulae description="In-line Formulae" end="tail"?>
