发明名称 EXHAUST GAS PURIFICATION CATALYST AND ITS PRODUCTION METHOD
摘要 <P>PROBLEM TO BE SOLVED: To provide an exhaust gas purification catalyst excellent in thermal durability. <P>SOLUTION: This exhaust gas purification catalyst has a rhodium particle (1), a plurality of compound particles (2) which carry the rhodium particle (1), surround the circumference of the particle, and are oxides whose main components contain Zr, and a cluster (10). Furthermore, the exhaust gas purification catalyst has particles of a plurality of the oxides (3) which are formed around the cluster (10), surround the circumference of the cluster, and suppress the coagulation of the compound particles (2). <P>COPYRIGHT: (C)2012,JPO&INPIT
