    Abstract: 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 any suitable configuration including at least a substrate and a washcoat, where the substrate has a plurality of channels, suitable porosity, offers a three-dimensional support for the washcoat, and is made of any suitable material. The washcoat may be deposited on the substrate by any suitable method, and may include a mixture of at least one or more carrier material oxides and one or more catalysts. Suitable materials for the carrier material oxides may include titanium dioxide, tin dioxide, and zirconium dioxide, among others, excluding aluminum oxide (Al2O3), which may serve for a decrease of sulfur trioxide emissions and consequently of sulfuric acid mist. Suitable catalysts within the washcoat may include platinum, palladium, rhodium, and iridium, among others.

    Abstract: Synergized Platinum Group Metals (SPGM) catalyst system for TWC application is disclosed. Disclosed SPGM catalyst system may include a washcoat with a Cu—Mn spinel structure and an overcoat that includes PGM supported on carrier material oxides, such as alumina. SPGM catalyst system shows significant improvement in nitrogen oxide reduction performance under stoichiometric operating conditions and especially under lean operating conditions, which allows a reduced consumption of fuel. Additionally, disclosed SPGM catalyst system also enhances the reduction of carbon monoxide and hydrocarbon within catalytic converters. Furthermore, disclosed SPGM catalyst systems are found to have enhanced catalyst activity compared to commercial PGM catalyst system, showing that there is a synergistic effect among PGM catalyst and Cu—Mn spinel within the disclosed SPGM catalyst system.

    Abstract: The effect of aging temperature on oxygen storage materials (OSM) substantially free from platinum group (PGM) and rare earth (RE) metals is disclosed. Samples of ZPGM-ZRE metals OSM, hydrothermally aged at a plurality of high temperatures are found to have significantly high oxygen storage capacity (OSC) and phase stability than conventional PGM catalysts with Ce-based OSM. ZPGM-ZRE metals OSM includes a formulation of Cu—Mn stoichiometric spinel structure deposited on Nb—Zr oxide support and may be converted into powder to be used as OSM application or coated onto catalyst substrate. ZPGM-ZRE metals OSM, after aging condition, presents enhanced level of thermal stability and OSC property which shows improved catalytic activity than conventional PGM catalysts including Ce-based OSM. ZPGM-ZRE metals OSM may be suitable for a vast number of applications, and more particularly in underfloor catalyst systems.
