20100004123 | OXYGEN STORAGE MATERIAL - An excellent oxygen storage capacity is achieved even in the case used for a long period of time under high temperature conditions. An oxygen storage material contains a first particle made of a composite oxide of cerium and zirconium or a composite oxide of cerium, a rare-earth element other than cerium and zirconium, a second particle including a composite oxide of a rare-earth element, an alkaline-earth element and zirconium, and a precious metal. A part of the precious metal forms a solid solution with the composite oxide included in the second particle. | 01-07-2010 |

20110237428 | EXHAUST GAS-PURIFYING CATALYST - The exhaust gas-purifying catalyst includes a substrate provided with one or more through-holes through which exhaust gas flows, and a catalyst layer which is supported by the substrate and contains precious metals and an oxygen storage material. The exhaust gas-purifying catalyst contains a first part to which the exhaust gas is supplied, and a second part to which the exhaust gas having passed through the first part is supplied and is smaller in the content of the oxygen storage material per unit volume than that of the first part. | 09-29-2011 |
20120040824 | EXHAUST GAS-PURIFYING CATALYST - 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. | 02-16-2012 |
20120295787 | EXHAUST GAS PURIFYING CATALYST - An exhaust gas purifying catalyst includes a catalyst powder that includes a ceria-zirconia composite oxide on which platinum (Pt) is supported, and a Ce/alumina powder that includes alumina which contains cerium (Ce) in the structure thereof. The Ce/alumina undergoes only a slight decrease in specific surface area even in a lean atmosphere at a high temperature. The Pt supported on the ceria-zirconia composite oxide forms a Pt—O—Ce bond with the Ce present on surfaces of Ce/alumina so that migration of Pt is restrained and sintering of Pt is prevented. | 11-22-2012 |

20130216940 | SUPPORTED CATALYST FOR FUEL CELL, METHOD OF MANUFACTURING THEREOF, AND FUEL CELL - An object of the present invention is to provide a supported catalyst for a fuel cell having a high activity, a method of manufacturing thereof, and a fuel cell including the supported catalyst for a fuel cell. A supported catalyst for a fuel cell of the present invention includes a conductive carrier and catalyst particle supported on the conductive carrier and contains platinum. The ratio of the mass of oxygen to the mass of the catalyst particle measured by using an inert gas fusion-nondispersive infrared absorption method is 4 mass % or less. | 08-22-2013 |

20090318284 | NITROGEN OXIDE ADSORBENT AND METHOD FOR PRODUCING THE SAME - This method for producing a nitrogen oxide adsorbent comprising zeolite loaded with Fe by ion exchange comprises an impregnation step of impregnating zeolite with an aqueous solution of ferric chloride, and a heat treatment step of heating the zeolite impregnated with the aqueous solution of the ferric chloride to a temperature at or above a boiling point of the ferric chloride, thereby loading the zeolite with Fe by ion exchange. By impregnating zeolite with an aqueous solution of ferric chloride and then heating the impregnated zeolite to a predetermined temperature, a large amount of iron can reach ion exchange sites in zeolite, though the reason is not clear. As a result, a resulting Fe-zeolite nitrogen oxide adsorbent improves in ability to adsorb nitrogen oxides. | 12-24-2009 |
