COMPOSITE COMBINING MONOLAYER OR MULTILAYER OF ZEOLITE MOLECULAR SIEVE OR ITS ANALOGUE ONTO A SUBSTRATE AND PREPARATION THEREOF

摘要

The present invention relates to a zeolite-substrate composite having a zeolite monolayer or multilayer bound on the surface of the substrate, comprising (i) a substrate selected from a group consisting of a substrate having surface hydroxyl groups, a metal substrate capable of reacting with thiol groups, and a polymeric materials having reactive functional groups at its main or side chain, (ii) molecular sieve particles selected from porous oxides or sulfides having surface hydroxyl groups, and (iii) a linker derived from a linking compound having at least two functional groups at both terminal ends, of which one is chemically bonded to said substrate and the other is chemically bonded to said zeolite; wherein said chemical bonding of linker to the substrate and zeolite or its analog is achieved by any of covalent bonds, ionic bonds, and/or coordination bonds, and a method of preparing the same.
