摘要： Described are catalytic articles comprising a substrate having a washcoat on the substrate, the washcoat containing a catalytic component having a first average (D50) particle size and a functional binder component having a second average (D50) particle size in the range of about 10 nm to about 1000 nm, wherein the ratio of the first average (D50) particle size to the second average (D50) particle size is greater than about 10:1. The catalytic articles are useful in methods and systems to purify exhaust gas streams from an engine.

摘要： Provided herein is a barium sulfate-containing catalyst carrier. The catalyst carrier is useful for supporting an exhaust gas purification catalyst, such as a three way conversion catalyst. In an embodiment, the carrier comprises BaSO4/thermally stable alumina. Further provided is a process for preparing the catalyst carrier, with or without precious metals, comprising treating a barium oxide/alumina or barium carbonate/alumina with a stoichiometric amount of sulfuric acid (H2SO4), thus forming BaSO4/alumina in situ in good yield and at low cost.
