ABSTRACT:
A three-way catalyst for automotive emission control having a mechanical carrier having a support comprised substantially of alumina, a lanthanum oxide coating decorated onto the support, a catalytic compound discontinuously supported on the decorated support having a major constituent of palladium, and a discontinuous phase of titanium oxide on the alumina, lanthana, and catalytic compound composite.
The method of making such three-way catalyst for automotive emission control, comprises coating an alumina support with lanthana, impregnating the coated support with a palladium compound to form a discontinuous phase on the lanthana, and impregnating the coated support and catalytic compound with an organo-titania compound to form a discontinuous phase on the lanthana and palladium compound.
