Mixed particles and honeycomb structure

摘要

The mixed particles of the present invention comprises: noble metal particles of a noble metal; first particles of one or more metal oxides selected from the group consisting of Al 2 O 3 , SiO 2 , ZrO 2 and TiO 2 ; and second particles of a metal oxide having a larger adsorptive interaction with the noble metal of the noble metal particles as compared with the metal oxide of the first particles.
It becomes possible to provide the mixed particles and honeycomb structure capable of suppressing sintering of platinum.
