ZEOLITE CORE/SILICA ZEOLITE SHELL COMPOSITES, METHOD OF PREFARING THE SAME AND CATALYSTIC USE THE SAME

摘要

The present invention relates to a preparation method of a zeolite core/silica zeolite shell composite, the zeolite core/silica zeolite shell composite prepared by the preparation method, and a use of the zeolite core/silica zeolite shell composite. More particularly, the preparation method of a zeolite core/silica zeolite shell composite comprises a step of growing a silica zeolite shell having a crystal structure coherent to a zeolite seed crystal by adding and crystallizing the zeolite seed crystal to a gel solution including a silicon-source compound, a structure directing agent, and a fluorine anion-source compound.
