  • Method for preparing porous organic-inorganic hybrid materials
    Patent number: 9175025
    Abstract: The present invention relates to a method for preparing a porous organic-inorganic hybrid, which comprises gelling a reaction mixture containing a metal precursor, a water-soluble additive and water or water-containing organic solvent at a gelling temperature of 30° C.˜100° C. to obtain an organogel-containing solution having a viscosity of 2 to 50,000 (cps), subsequently ageing the solution at said gelling temperature under stirring; and subsequently heating the organogel-containing solution at a temperature between said gelling temperature and 250° C. to crystallize the solution.
    Type: Grant
    Filed: June 1, 2012
    Date of Patent: November 3, 2015
    Assignee: KOREA RESEARCH INSTITUTE OF CHEMICAL TECHNOLOGY
    Inventors: U-Hwang Lee, Jong-San Chang, Young Kyu Hwang, You-Kyong Seo, Christian Serre, Patricia Horcajada Cortes, Hubert Chevreau, Florence Ragon, Thomas Devic
