Zeolite structure and manufacturing method thereof

摘要

There is disclosed a zeolite structure 100 comprising a zeolite base material 4 having a honeycomb shape and including partition walls 1 disposed to form a plurality of cells 2 which become through channels of a fluid and extend from one end face 11 to the other end face 12, the partition walls 1 contain a zeolite ion-exchanged with metal ions, a pore diameter distribution of the partition walls in a case where the abscissa indicates a pore diameter and the ordinate indicates a log differential pore volume is represented by a curve having a first maximum point in a range of pore diameters from 0.002 to 0.05 µm and a second maximum point in a range of pore diameters from 0.06 to 10 µm, and a value obtained by dividing a first maximum value which is a maximum value at the first maximum point by a second maximum value which is a maximum value at the second maximum point is from 1.0 to 20. A zeolite structure 100 having an excellent exhaust gas purification performance and an excellent strength is provided.
