ABSTRACT:
A honeycomb structure includes a first end face, a second end face, a honeycomb unit, and an ammonia adsorbing material. The second end face is located opposite to the first end face along a longitudinal direction of the honeycomb structure. The honeycomb unit has plural cell walls extending along the longitudinal direction from the first end face to the second end face to define plural cells. The cell walls include a NOx adsorbing material and an inorganic binder. The ammonia adsorbing material is supported on the cell walls. An amount of the ammonia adsorbing material supported on the cell walls is varied between the first end face and the second end face.
