摘要: A particulate mixture composed of noble metal particles, the first particles made of at least one metal oxide selected from the group consisting of Al2O3, SiO2, ZrO2 and TiO2, and the second particles made of a metal oxide having higher adsorptivity for the noble metal of the noble metal particles metal than that of the metal oxide of the first particles, wherein the majority of the noble metal particles are supported on the second particles with the minority thereof on the first particles.
