Abstract: The disclosure provides a platinum-containing three-way conversion (TWC) catalyst, and a system for treating an exhaust gas stream from a gasoline engine using the TWC catalyst. The system is configured to introduce controlled quantities of hydrogen gas into the exhaust gas stream upstream of the platinum-containing TWC catalyst article during a cold-start period. Further provided are related methods of treating such exhaust streams. Such systems and methods are useful in reducing a level of one or more of hydrocarbons, carbon monoxide, and nitrogen oxide in a gaseous exhaust stream from a gasoline engine.

Abstract: A photocatalyst laminate which is composed of an undercoat layer provided on a substrate and a photocatalyst layer laminated on the surface of the undercoat layer. The undercoat layer contains (A) 100 parts by mass of a resin component and (B) 0.1-50 parts by mass of fine core-shell particles, each of which has a core that is formed of a fine tetragonal titanium oxide solid solution particle wherein tin and manganese are solid-solved and a shell that is formed from silicon oxide on the outside of the core. This photocatalyst laminate is not susceptible to decrease in the photocatalyst function even under outdoor exposure for a long period of time, and is thus capable of providing a coated article that exhibits excellent weather resistance.
