摘要： An exhaust gas-purifying catalyst includes a support provided with one or more through-holes through which exhaust gas flows, and a catalytic layer supported by the support and containing an oxygen storage material. The exhaust gas-purifying catalyst includes a first section to which the exhaust gas is supplied, and a second section to which the exhaust gas having passed through the first section is supplied. The catalytic layer includes a layered structure of a first catalytic layer containing platinum and/or palladium and a second catalytic layer containing rhodium in the first catalytic section and further includes a third layer containing rhodium in the second section. The second section is smaller in oxygen storage material content per unit volumetric capacity than the first section.

摘要： The present invention is directed to address the following problem: in an exhaust gas purification catalyst comprising a dual catalyst of a combination of a startup catalyst and an underfloor catalyst, reduction in the gas diffusivity of the underfloor catalyst results in reduction in the use efficiency of a catalytic active site, resulting in reduction in purification performance. The present invention relates to an exhaust gas purification catalyst comprising a dual catalyst of a combination of a startup catalyst and an underfloor catalyst having a catalyst coating where a large number of voids are included, wherein high-aspect-ratio pores having an aspect ratio of 5 or more account for a certain rate or more of the whole volume of the voids, to thereby enhance the purification performance of the catalyst.

摘要： The present invention provides an exhaust gas purification catalyst comprising a base material, and a two or more layered catalyst coating layer, formed on the base material, wherein the two or more layers have upper and lower layers, and wherein the upper layer contains a large amount of noble metal per liter of the base material more than that of the lower layer, and the lower layer contains a large amount of an oxygen storage/release material per liter of the base material more than that of the upper layer. This exhaust gas purification catalyst has more excellent H2S purifying performance than conventional catalysts while maintaining purifying performance against NOx and the other exhaust gas components.
