Abstract
A catalyst body is composed of a porous support made mainly of cordierite. Single crystals of at least one kind of zeolite such as silicalite are formed directly on the surface of the porous support. Al2O3, SiO2 are component elements forming the porous support and used as a seed crystal for growing the single crystals of zeolite on the surface of the porous support. Further, the catalyst made of noble metal such as Pt is supported on the single crystals of zeolite.
