Abstract

The present invention relates to a single-crystal hollow ZSM-5 zeolite. Particles of single-crystal hollow ZSM-5 zeolite have a single-crystal structure, exhibit hexagonal morphology, and have a double-layered cavity structure nested inside and out, wherein an inner-layered cavity is at least partially enclosed by a first wall layer of zeolite, and an outer-layered cavity is completely enclosed by a second wall layer of zeolite, and wherein a ratio of a length of crystal grain of the zeolite to a length of the outer-layered cavity is 1.1-2.0, and a ratio of a width of crystal grain of the zeolite to a width of the outer-layered cavity is 1.05-1.5. The present invention also relates to a preparation method and use of the single-crystal hollow ZSM-5 zeolite.
