The present invention relates to a complex and a method for manufacturing same, the complex comprising: at least one crystalline hybrid nanoporous material powder, in which a metal ion, or a metal ion cluster to which oxygen is bound, and an organic ligand, or the organic ligand and a negative ion ligand are in a coordinate covalent bond; and at least one organic polymer additive, or at least one organic polymer additive and an inorganic additive, wherein the shape of the complex is spherical or pseudo-spherical, the size of the complex is 0.1 to 100 mm, a total volume of pores is 5 or more volume % based on the sum of a total volume of nanoporous material having a size of at most 10 nm and a total volume of pores having a size of at least 0.1 &#x3bc;m, and wherein a non-surface value per weight (m/g) of the complex as at least 83% of a non-surface value per weight (m/g) of the nanoporous material powder.

Complex comprising crystalline hybrid nanoporous material powder

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&#xb0; C.&#x2dc;100&#xb0; 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&#xb0; C. to crystallize the solution. According to the method for preparation of the present invention, it is possible to commercially practice the present invention since the reaction can be carried out in water or a water-containing organic solvent at an ambient pressure or a slightly raised pressure under a reflux condition, as well as it is possible to mass-produce a porous organic-inorganic hybrid having a high crystallinity and a large surface even in a high mol ratio of 1:1&#x2dc;1:30 of solvent to metal.

Method for preparing porous organic-inorganic hybrid materials

Porous organic-inorganic hybrid materials with crystallinity and a method for preparing the same are provided. The method comprises preparing a reaction solution containing a mixture of at least one inorganic metal precursor, at least one organic compound which may act as a ligand, and a solvent (step 1); and forming porous organic-inorganic hybrid materials with crystallinity by reacting the reaction solution (step 2), wherein the reaction is carried out under the pressure of about 3 atm or less.
