  • Publication number: 20060219989
    Abstract: The present invention relates to a method for preparing a uniformly aligned zeolite supercrystal, which comprises growing a crystal of a zeolite or zeotype material in a uniformly aligned template, whereby said uniformly aligned zeolite supercrystal is prepared, and a uniformly aligned zeolite supercrystal. The uniformly aligned zeolite supercrystal of this invention would be anticipated to maximize its applicability by overcoming the shortcomings of zeolites with random orientation.

  • Patent number: 6693055
    Abstract: The present invention relates to a method for the preparation of a zeolite-substrate composite comprising a patterned zeolite monolayer or multilayer on a substrate, which comprises forming a pattern of a linking compound on the substrate by a selective irradiation with a UV ray, a selective application of a linking compound or a blocking compound, or a selective deposition of a metal, and combining zeolite particles on the portion whereon the linking compound is patterned. The substrate is selected from a group consisting of a substrate having surface hydroxyl groups, a metal capable of being reacted with thiol or amino groups, and a polymeric material having various surface functional groups. The present invention also relates to a zeolite-substrate composite comprising a patterned zeolite monolayer or multilayer on a substrate prepared by said method.
