| 20090088320 | EXHAUST GAS PURIFYING CATALYST AND PRODUCTION METHOD THEREOF - An exhaust gas purifying catalyst including: a plurality of first compounds | 04-02-2009 |
| 20090111688 | Exhaust Gas Purifying Catalyst and Production Method Thereof - An object is to maintain an effect of enhancing activity of noble metal particles by transition metal without increasing production cost and an environmental load. | 04-30-2009 |
| 20100113262 | HIGH HEAT-RESISTANT CATALYST AND MANUFACTURING METHOD THEREOF - A high heat-resistant catalyst includes: noble metal particles; first compounds which contact the noble metal particles and suppress movement of the noble metal particles; and second compounds which envelop the noble metal particles and the first compounds, suppress the movement of the noble metal particles, and suppress coagulation of the first compounds following mutual contact of the first compounds. The first compounds support the noble metal particles, and single piece or aggregate of the first compounds supporting the noble metal particles are included in a section partitioned by the second compounds. A coefficient of linear thermal expansion of the second compounds is 1.2×10 | 05-06-2010 |
| 20110094211 | EXHAUST GAS PURIFYING CATALYST - An exhaust gas purifying catalyst includes a monolithic substrate ( | 04-28-2011 |
| 20110111952 | EXHAUST GAS PURIFYING CATALYST AND METHOD FOR PRODUCING THE SAME - An exhaust gas purifying catalyst ( | 05-12-2011 |
| 20110160049 | EXHAUST GAS PURIFYING CATALYST AND METHOD FOR MANUFACTURING THE SAME - An exhaust gas purifying catalyst includes: rhodium; a zirconium-containing oxide which supports rhodium, and comprises: at least one element selected from the group consisting of calcium, lanthanum, cerium, neodymium and yttrium; and zirconium; and a NOx absorbing material comprising at least one selected from the group consisting of magnesium, barium, sodium, potassium and cesium. A degree of dispersion of rhodium is 20% or more after baking at 900° C. in air for three hours. A method for manufacturing the exhaust gas purifying catalyst includes: mixing the zirconium-containing oxide with water, thereby preparing an aqueous liquid of the zirconium-containing oxide; and supporting rhodium on the zirconium-containing oxide by mixing the aqueous liquid of the zirconium-containing oxide with an aqueous solution of a rhodium salt. A pH of a mixed liquid of the aqueous solution of the rhodium salt and the aqueous liquid of the zirconium-containing oxide is adjusted to 7 or more. | 06-30-2011 |
