摘要： The catalyst carrier in accordance with the present invention is a catalyst carrier comprising a support containing an oxide and an element in group 3A of the periodic table, and a coating part covering at least a part of a surface of the support; wherein the coating part contains an element in group 3A of the periodic table; and wherein the element in group 3A contained in the coating part has a concentration higher than that of the element in group 3A contained in the support. In this case, even when a catalyst in which rhodium is supported by the catalyst carrier is used for a long time in a high temperature environment, the grain growth of rhodium particles can be suppressed, and the catalyst can fully be prevented from lowering its activity.

摘要： Provided is an ambient temperature NOx adsorbent. The ambient temperature NOx adsorbent comprises a support and a metal supported on the support. The support comprises at least one metal oxide selected from oxides of Co, Fe, Cu, Ce, Mn, and a combination thereof. The supported metal comprises at least one metal selected from Cu, Co, Ag, Pd, and a combination thereof. The metal oxide is easily changed the oxidation number and has oxygen absorptive/emissive properties. The supported metal has an oxidative activity and is highly adsorptive to NO. Oxygen supplied from the metal oxide converts the supported metal to a peroxidized form of the supported metal. Hence, NO is readily adsorbed to the supported metal at ambient temperature around room temperature. The adsorbed NO is easily oxidized to NO2 by oxygen supplied from the metal oxide or the supported metal in a peroxidized state in the absence of oxygen in an ambient atmosphere. The NO2 is then efficiently adsorbed to the metal oxide. That is, the ambient temperature NOx adsorbent can adsorb a sufficient amount of NOx even at ambient temperature around room temperature.
摘要翻译：提供了环境温度的NOx吸附剂。环境温度NOx吸附剂包括支撑体和支撑在支撑体上的金属。载体包括选自Co，Fe，Cu，Ce，Mn的氧化物中的至少一种金属氧化物及其组合。负载金属包含至少一种选自Cu，Co，Ag，Pd及其组合的金属。金属氧化物容易地改变氧化数并具有吸氧/发射性能。负载金属具有氧化活性，对NO具有高吸附性。从金属氧化物供应的氧将负载的金属转化为过氧化形式的负载金属。因此，在室温附近的环境温度下，NO容易被吸附到负载的金属上。通过在环境气氛中不存在氧气的过氧化态从金属氧化物或负载金属供给的氧，吸附的NO容易被氧化成NO2。然后将NO 2有效地吸附到金属氧化物上。也就是说，环境温度NOx吸附剂即使在室温附近的环境温度下也能吸附足够量的NOx。

摘要： A catalyst for purification of exhaust gas, in which a noble metal is supported on a metal oxide support, has a basic site content of 1 mmol/L-cat or less, as determined on the basis of an amount of CO2 desorbed per liter of the catalyst as measured by a CO2 temperature-programmed desorption method.
