Abstract
A catalyst support is formed from powders of silica, titania and vanadia and optionally a silicate-based clay by applying a wet mixture of such powders to a support substrate and drying and calcining. When impregnated with platinum or palladium, the catalyst support reduces hydrocarbon and particulate emission in diesel exhaust and also prevents formation of mutagens in the exhaust. Advantageously, the catalyst support minimizes reaction with sulfur.
