Abstract: A fuel cell supported catalyst includes an underlying support structure having at least one of a metal oxide and a metal phosphate. Catalyst particles are arranged onto and in engagement with the support structure. An intermediate conductive, corrosion-resistant layer, such as boron-doped-diamond, is arranged onto and in engagement with the support structure to surround the catalyst particles. The supported catalyst is produced by depositing the intermediate layer onto the support structure after the catalyst particles have been deposited on the underlying support structure, in one example. In another example, voids are provided in the intermediate layer, which has been deposited onto the underlying support structure, to subsequently receive the catalyst particles.

Abstract: Disclosed is a particulate filter, which is adapted to be disposed in an exhaust passage of an engine to trap particulate matter contained in exhaust gas discharged from the engine. The particulate filter comprises a filter body having a porous partition wall which defines a plurality of exhaust gas channels allowing the exhaust gas to pass therethrough, and a catalyst layer formed on a surface of the porous partition wall. The catalyst layer includes a Zr-based composite oxide which contains zirconium (Zr), and a rare-earth metal except cerium, wherein a content ratio of an oxide of the non-cerium rare-earth metal to a total amount of ZrO2 and the oxide of the non-cerium rare-earth metal in the Zr-based composite oxide is set in the range of greater than 33 mol % to less than 40 mol %. The particulate filter of the present invention can achieve a higher PM burning rate to burn PM within a shorter period of time. In addition, the higher PM burning rate makes it possible to provide enhanced fuel economy performance in an engine designed to perform a post-injection control.

In addition, the higher PM burning rate makes it possible to provide enhanced fuel economy performance in an engine designed to perform a post-injection control.

Abstract translation: 公开了一种微粒过滤器，其适于设置在发动机的排气通道中以捕集从发动机排出的废气中所含的颗粒物质。 颗粒过滤器包括具有多孔分隔壁的过滤体，该多孔分隔壁限定允许废气通过的多个废气通道，以及形成在多孔分隔壁的表面上的催化剂层。 催化剂层包括含有锆（Zr）的Zr基复合氧化物和除了铈之外的稀土金属，其中非铈铈稀土金属的氧化物与ZrO 2的总量的含量比和 Zr系复合氧化物中的非铈稀土类金属的氧化物的含量设定在大于33摩尔％至小于40摩尔％的范围内。 本发明的微粒过滤器可以在更短的时间内实现更高的PM燃烧速率来燃烧PM。 此外，较高的PM燃烧速率使得可以在设计成执行后喷射控制的发动机中提供增强的燃料经济性能。
