ULTRAPOROUS ORGANIC-INORGANIC NANOPOROUS COMPOSITES FORMED BY COVALENT BONDING BETWEEN INORGANIC-ORGANIC HYBRIDS AND MESOCELLULAR MESOPOROUS MATERIALS

摘要

PURPOSE: Ultraporous organic-inorganic composites produced with inorganic-organic hybrids covalent-bonded with mesocellular mesoporous materials are provided to secure wide surface area, multiple pore structure, large-scale pore volume, and chain flexibility. CONSTITUTION: Ultraporous organic-inorganic composites are produced with inorganic-organic hybrids covalent-bonded with mesocellular mesoporous materials. The mesocellular mesoporous materials have organic groups on the surface thereof. A method for producing the ultraporous organic-inorganic composites comprises the following steps of: mixing organic precursor, inorganic precursor, and surfactant and allowing them to react to obtain mesoporous cellular foam MCF-R; adding the mesoporous cellular foam MCF-R to a mixed precursor solution of metal-organic frameworks(MOF) and non-porous organic-inorganic hybrids(NOIH); and crystallizing the MCF-R-MOF ultraporous organic-inorganic composites.
