  • Publication number: 20100008990
    Abstract: The invention describes a new class of crystalline silica material having two levels of porosity and structural order. At the first level, building units are nanoslabs of uniform size having zeolite framework. At the second structural level, nanoslabs are assembled, e.g. linked through their corners, edges or faces following patterns imposed by interaction with cationic surfactant or triblock copolymer molecules. After evacuation of these molecules, microporosity is obtained inside the nanoslabs, and a precise mesoporosity between the nanoslabs depending on the tiling pattern of the zeolite nanoslabs, as evidenced by X-ray diffraction. These materials are useful for the fixation of biologically active species, such as poorly soluble drugs.

  • Patent number: 7344694
    Abstract: A series of crystalline alumino-silicate zeolites identified as UZM-12 have been synthesized. These UZM-12 compositions have the ERI topology, a Si/Al>5.5 and can be prepared as nanocrystallites having an average particle size of about 15 to about 50 nanometers and a spheroidal morphology. The UZM-12 composition can be treated to remove at least a fraction of the framework aluminum atoms thereby providing zeolites with a Si/Al>5.75 and identified as UZM-12HS. Both the UZM-12 and UZM-12HS can catalyze various hydrocarbon conversion processes.
