Abstract: A honeycomb structure body has promoter particles made of ceria-zirconia solid solution, and inorganic binder particles made of alumina arranged between the promoter particles, and a cerium aluminate phase formed on a boundary surface between the promoter particles and the inorganic binder particles. Further, a method of producing the honeycomb structure body has at least first and second steps. The first step molds raw material to form a honeycomb molded body. The raw material has a mixture of promoter particles and a sol containing inorganic binder particles. The second step fires the honeycomb molded body in an atmosphere having an oxygen concentration of not more than 0.5 vol. % to produce the honeycomb structure body.

Abstract: A porous honeycomb structure including multiple co-catalyst particles and multiple inorganic binder particles of smaller particle diameter than the co-catalyst particles. Each co-catalyst particle is comprised of a ceria-zirconia solid solution. The inorganic binder particles reside between the co-catalyst particles. In the honeycomb structure, an exposure fraction of the co-catalyst particles from the inorganic binder particles on a cross-section of the honeycomb structure is within a range of 3 to 10%.
