Abstract

A method of making an oxidation catalyst for use in automotive exhaust gas treatment by impregnating with platinum a mechanical carrier having a support comprised substantially of alumina to produce a composite having, by weight, 1-5% platinum, and impregnating (by incipient wetness) the composite with an organo-titanium compound (titanium butoxide) and decomposing such compound to form a discontinuous titanium oxide phase on or adjacent the exposed portions of the composite. A method of treating automotive exhaust gases carrying hydrocarbons is also disclosed, comprising initiating combustion in an internal combustion engine fueled with fossil fuel, placing an oxidation catalyst at a location in close proximity to the source of such emissions, and exposing at such location the exhaust gases to a catalyst consisting of an Al.sub.2 O.sub.3 substrate, a continuous coating of platinum in an amount of 0.1-5% by weight, and a complexing discontinuous phase of titania thereover in an amount of 0.1-2.5%.
