摘要： PROBLEM TO BE SOLVED: To provide a catalyst for cleaning exhaust gas, the high-temperature durability of which is made excellent by further increasing the thermal stability of Rh. SOLUTION: The catalyst for cleaning exhaust gas is characterized in that a particle of a first oxide carrier 10, with which Rh can form a solid solution, and that of a second oxide carrier 11, in which the solid solubility limit of Rh is made lower than that of Rh in the first oxide carrier 10 and with which the first oxide carrier 10 does not form the solid solution, are mixed with each other and Rh is deposited on the first oxide carrier 10 at the least. Rh is made solid-soluble and dispersed in an atomic state in the first oxide carrier 10 in a lean atmosphere and is reduced in a rich atmosphere to become minute metal Rh. Since the atomic state and metal state of Rh are repeated, the grain growth of Rh is restrained and the deterioration of the catalyst for cleaning exhaust gas is prevented.

摘要： PROBLEM TO BE SOLVED: To maintain the high dispersion support state of a noble metal even after endurance at a high temperature and to further prevent the lowering of activity. SOLUTION: The noble metal is supported on a carrier of hollow particles of amorphous alumina and/or transitional alumina added with a rare earth element at the atomic ratio in terms of a metal element of 1-8 mol% to the alumina. The noble metal is partially dissolved in the carrier as a solid solution and partially deposited as fine particles of several nanometers or below in particle size on the carrier. The pore volume of the carrier increases largely to improve the diffusion of gas. Since the noble metal is deposited as fine particles, the deposited noble metal is easily re-dissolved in the carrier during the use in an oxidative atmosphere and the dissolved noble metal is easily re-deposited during the use in a reductive atmosphere. Therefore, the growth of the noble metal particles is suppressed. COPYRIGHT: (C)2004,JPO
