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 NO x adsorbent. The ambient temperature No x 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 NO 2 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 NO 2 is then efficiently adsorbed to the metal oxide. That is, the ambient temperature NO x adsorbent can adsorb a sufficient amount of NO x even at ambient temperature around room temperature.
摘要翻译：所提供的是环境温度NO x吸附剂。环境温度No x x吸附剂包括载体和支撑在载体上的金属。载体包含选自Co，Fe，Cu，Ce，Mn的氧化物及其组合的至少一种金属氧化物。所述负载金属包含选自Cu，Co，Ag，Pd及其组合中的至少一种金属。金属氧化物容易改变氧化数并具有氧吸收/发射性能。被支撑的金属具有氧化活性并且对NO具有高度吸附性。由金属氧化物供应的氧将载体金属转化为过氧化形式的载体金属。因此，在室温附近的环境温度下，NO容易被吸附到负载金属上。被吸附的NO在环境气氛中在氧气不存在的情况下通过从过氧化态的金属氧化物或负载金属提供的氧容易地被氧化成NO 2。然后NO 2有效地吸附到金属氧化物上。也就是说，即使在室温左右的环境温度下，环境温度下的NO x吸附剂也能够吸附足够量的NO x。
