【Task】 The present invention provides a zeolite having a catalyst surface that is nanoporous and has the characteristics of zeolite, a method for producing the same, and a zeolite catalyst using the same. [Solution] In the present invention, a zeolite obtained by dealumination of a synthetic zeolite and dealuminated with a metal oxide precursor in which nanopores are formed by calcining are mixed in the presence of water and calcined at least on the surface. More specifically, the present invention relates to a composite zeolite having nanopores, and more particularly, to the composite zeolite in which at least a part of the surface of the composite zeolite is covered with a nanopore metal oxide, a method for producing them, and a catalyst using the composite zeolite.
