Catalyzed particulate filters comprise three-way conversion (TWC) catalytic material, which comprises rhodium as the only platinum group metal, that permeates walls of a particulate filter. Such catalyzed particulate filters may be located downstream of close-coupled three-way conversion (TWC) composites in an emission treatment system downstream of a gasoline direct injection engine for treatment of an exhaust stream comprising hydrocarbons, carbon monoxide, nitrogen oxides, and particulates.

Monometallic rhodium-containing four-way conversion catalysts for gasoline engine emissions treatment systems

A layered catalyst composite for the treatment of exhaust gas emissions, effective to provide lean NOtrap functionality and three-way conversion functionality is described. Layered catalyst composites can comprise catalytic material on a substrate, the catalytic material comprising at least two layers. The first layer comprising rare earth oxide-high surface area refractory metal oxide particles, an alkaline earth metal supported on the rare earth oxide-high surface area refractory metal oxide particles, and at least one first platinum group metal component supported on the rare earth oxide-high surface area refractory metal oxide particles. The second layer comprising a second platinum group metal component supported on a first oxygen storage component (OSC) and/or a first refractory metal oxide support and, optionally, a third platinum group metal supported on a second refractory metal oxide support or a second oxygen storage component.

Integrated LNT-TWC catalyst

Diesel exhaust treatment articles, systems and methods are disclosed. According to one or more embodiments, an oxygen storage component is utilized and degradation of the oxygen storage component is correlated with degradation of the hydrocarbon conversion efficiency of a catalyst in a diesel engine system.
