Platinum-bismuth catalysts for treating engine exhaust

An engine exhaust catalyst containing precious metal nanoparticles is promoted with bismuth. The bismuth promotion improves the catalyst's CO oxidation performance. Also, by varying the amount of bismuth that is added, the NO conversion rate that can be realized with the catalyst can be controlled. The control over the NO conversion rate is important because the passive regenerative performance of a particulate filter used in engine exhaust systems is based on the amount NO 2 that is present in the exhaust stream that reaches the particulate filter. The amount of NO 2 being produced needs to be optimized (not necessarily maximized) so that adequate particulate filter regeneration performance can be maintained while avoiding unused, toxic NO 2 from being exhausted into the atmosphere.

Visible light-responsive photocatalyst and method for producing the same

It is intended to provide a titanium oxide photocatalyst and a photocatalytic functional member which can exhibit a high photocatalytic activity under visible light irradiation and can be mass-produced. A visible light-responsive photocatalyst having bismuth enriched on the surface thereof is obtained by mixing a bismuth compound with titanium oxide and baking the resulting mixture to allow titanium oxide to carry bismuth. Further, when bismuth in a bismuth oxide is contained as low-dimensional bismuth, a visible light-responsive photocatalyst with a higher activity is obtained. When the titanium oxide contains at least one element selected from Si, Zr, Al, W, Mo, Mg, Hf and B, an effect of the Bi compound on increasing the visible light-responsive photocatalytic activity is further enhanced. The atomic ratio of Bi/Ti is preferably set to 0.0001 or more and 10 or less. The effect of carrying of the low-dimensional bismuth oxide on increasing photocatalyst can be applied also to a commercially available titanium oxide photocatalyst.

Platinum-bismuth catalysts for treating engine exhaust

귀금속 나노입자를 포함하는 엔진 배기가스 촉매는 비스무트로 활성화된다. 비스무트 활성은 촉매의 일산화탄소 산화 작용을 향상시킨다. 또한, 추가되는 비스무트의 양을 다양화함으로써, 촉매로 구현되는 NO 전환율 조절이 가능해진다. 엔진 배기가스 시스템에 사용되는 미립자 필터의 수동 재생 작용이 미립자 필터에 도달하는 배기가스 흐름에 존재하는 NO 2 의 양에 기반을 두고 있기 때문에 NO 전환율에 대한 조절이 중요하다. 사용되지 않는 독성의 NO 2 가 대기중으로 배출되는 것을 피하는 한편 적절한 미립자 필터 재생 작용이 유지될 수 있도록 생산되는 NO 2 의 양이 최적화될 필요가 있다(반드시 최대화될 필요는 없다). Engine exhaust catalysts comprising precious metal nanoparticles are activated with bismuth. Bismuth activity enhances the carbon monoxide oxidation of the catalyst. In addition, by varying the amount of bismuth added, it is possible to control the NO conversion implemented by the catalyst. Control of NO conversion is important because the passive regeneration of particulate filters used in engine exhaust systems is based on the amount of NO 2 present in the exhaust stream reaching the particulate filter. The amount of NO 2 produced needs to be optimized (not necessarily maximized) to avoid the release of unused toxic NO 2 into the atmosphere while maintaining adequate particulate filter regeneration.
