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
