摘要： A catalytic material including particles formed of a catalytic core material having a thermally resistant porous shell coated over the catalytic core material. An oxygen storage material is dispersed within the thermally resistant porous shell. In an example, the oxygen storage material is ceria. The catalytic material can further include a catalytic support, wherein the particles are deposited on the catalytic support. The catalytic support can be a powdered oxide including a material selected from the group consisting of alumina, silica, zirconia, niobia, ceria, titania, and combinations thereof. The catalytic core can include an element selected from the group consisting of Pt, Pd, Rh, Co, Ni, Mn, Cu, Fe, Au, Ag, and combinations thereof. The porous shell can be selected from materials consisting of alumina, baria, ceria, magnesia, niobia, silica, titania, yttria, and combinations thereof.

摘要： A catalyst system includes an oxygen storage and release material that has at least one compound of the structure YMO3+δ, where M is selected from Mn, Co, Cu, Ce, Ti, Ni, Zn, Fe and any combination thereof, and where δ is ≥0. The oxygen storage and release material is configured to allow absorption and release oxygen depending on the conditions of a reagent stream such that sufficient oxygen is maintained for the catalytic removal of at least one of incompletely combusted hydrocarbons, CO, and NO. The catalyst system is useful in a catalytic converter such that oxygen is supplied under rich combustion conditions in an engine upstream of the catalytic converter inlet and oxygen is adsorbed and absorbed under lean rich combustion conditions in the engine.
