Document Type and Number:
Japanese Patent JP4992773
Kind Code:
B2
Abstract:
In a ceramic honeycomb structure (2), a catalyst material (1) used for burning soot discharged from an internal combustion engine is supported on partition walls (22) that are inner surfaces of cells (3). For example, a catalyst material to be used for burning carbon includes silver and alumina as components, and the catalyst material has a dumbbell-shaped O-Ag-O structure. Thus, the ceramic honeycomb structure can burn soot at low temperature using the supported catalyst material without corroding the honeycomb structure.
