<p>A diesel oxidation catalyst (DOC) catalytic converter for at least the conversion of carbon monoxide and hydrocarbons, removal of a fraction of particulate matter, and decrease of sulfur trioxide emissions within exhaust gases from an engine and consequently of sulfuric acid, is disclosed. The DOC may include a substrate and a washcoat, where the substrate has a plurality of channels, suitable porosity, and offers a three-dimensional support for the washcoat, which includes a mixture of at least one or more carrier material oxides and one or more catalysts. Suitable carrier material oxides include titanium dioxide, tin dioxide, and zirconium dioxide. Suitable catalysts within the washcoat include platinum, palladium, rhodium, and iridium.</p> |
