A combined hydrocarbon/ozone converter includes a substrate, a metal oxide washcoat and a hydrocarbon converting catalyst, such as platinum. The metal oxide washcoat comprises an ozone reacting component, such as cobalt oxide, and a non-catalytic component, such as aluminum oxide. The weight ratio of the hydrocarbon converting catalyst to the ozone reacting component may be between about 1:5 and about 1:100.
