Perovskite catalytic compositions having crystal structures and containing metals of the platinum group |
| abstract |
ABSTRACT OF THE DISCLOSURE Metal oxides of the type /A11-xA2x//B'1-yMey/O3 having perovakite-type crystal structures in which A1 and A2 are each one or more mono-, di-, or trivalent metals having ionic radii between about 0.8 and 1.65 Angstroms; B' is one or more metals having ionic radii between about 0.4 and 1.4 Angstroms; Me is one or more metals of the platinum group (ruthenium, osmium, rhodium, iridium, palladium, and platinum); x is between about 0.01 and 0.99; and y is between about 0.01 and 0.20 are useful as catalyssts for the oxidation of hydrocarbons and carbon monoxide and for the reduction of nitrogen oxides under conditions typical of those involved in the cleanup of the exhaust gases of internal combustion engines. |
