    摘要： Mesoporous hexagonal, cubic, lamellar, wormhole, or cellular foam aluminosilicates, gallosilicates and titanosilicates derived from protozeolitic seeds using an ionic structure directing agent are described. The silicon and aluminum, gallium or titanium centers in the structures are stable so that the framework of the structure does not collapse when heated in the presence of water or water vapor (steam). The steam stable compositions can be used as catalysts for hydrocarbon conversions, including the fluidized bed catalytic cracking and the hydrocracking of petroleum oils, and other reactions of organic compounds.

    摘要： A neutral templating route to mesoporous molecular sieves based on H-bonding and self-assembly between neutral primary amine or diamine surfactants (S°) and neutral inorganic precursors (I°) has been used to prepare hexagonal and lamellar mesoporous silicas with site isolated transition metal centers. This templating approach allows for the preparation of hexagonal or hexagonal-like mesoporous oxidation catalysts with large framework wall thickness of at least about 17 Å, small elementary particle size (≦400 Å), and unique combinations of framework-confined mesopores and textural mesopores while at the same time providing for facile recovery of the neutral template by simple solvent extraction. The templating of neutral metallosilicate precursors (I°) with neutral diamine surfactants (S°—S°) affords thermally stable pillared lamellar metallosilicates exhibiting complementary framework-confined microporosity and textural mesoporosity while at the same time also providing for template recovery by solvent extraction. In addition, a hexagonal transition metal-substituted catalysts, analogous to MCM-41, have been prepared using the mediated S+X·I+ templating pathway (Pathway 3) and mild reaction conditions. These new mesoporous metallosilicate molecular sieves exhibit exceptional catalytic activity for peroxide hydroxylation of benzene and oxidation of substituted aromatics with kinetic diameters that are too large (larger than 6 Å) to access the pore structure of the conventional microporous transition metal-substituted molecular sieves such as titano- and vanadosilicates.
