ABSTRACT:
A three-way catalyst for automotive emission control having a mechanical carrier having a support comprised substantially of alumina, a catalytic compound supported on said carrier having a major constituent of palladium, and a discontinuous phase of titanium oxide on or adjacent substantially each exposed particle of the catalytic compound.
A method of making a three-way catalyst for automotive emission control, comprising: impregnating with palladium a mechanical carrier having a support comprised substantially of alumina to produce a composite having 0.05-5.0% palladium; and impregnating the composite with an organo-titanium compound and decomposing such impregnated compound to form a discontinuous titanium oxide phase on or adjacent the exposed portions of said composite.
