Abstract
This invention is a sulfur-resistant, high surface area and temperature stabilized anatase crystal form of a mixed-oxide of titania and alumina comprising at least 40% molar amount titania. The mixed-oxide is made by co-hydrolysis of a mixture of the alkoxides of titanium and aluminum. The mixed oxide is useful as a catalyst support for treating exhaust gases generated by a diesel or gasoline internal combustion engine of automotive vehicles. The catalyst support may contain catalytic materials like precious metals.
