METHOD FOR PREPARING POROUS ORGANIC-INORGANIC HYBRID MATERIALS

Document Type and Number:

WIPO Patent Application WO/2012/165911

Kind Code:

A3

Abstract:

The present invention relates to a method for preparing porous organic-inorganic hybrid materials, which involves gelling a reaction mixture comprising a metal precursor, a water-soluble additive, and water or a water-containing organic solvent at a gelling temperature of 30°C to 150°C so as to acquire an organic gel-containing solution having a viscosity of 2 to 50,000 (cps); subsequently stirring and ageing the solution at said gelling temperature; and subsequently heating the organic gel-containing solution to a temperature between said gelling temperature and 250°C so as to crystallize the solution. According to the method for preparation of the present invention, a reaction may be performed with water or a water-containing organic solvent at an ambient pressure or a slightly raised pressure under a reflux condition, thus enabling the reaction to be performed in a commercially advantageous manner. Further, the reaction enables mass production of porous organic-inorganic hybrid materials having a high crystallinity and large surface area even at a high solvent to metal mole ratio of 1:1 to 30:1 with a time yield rate of at least 20 kg/m3.day.
