Patent ID: 8507399

Claim:
A porous organic-inorganic hybrid material with crystallinity which has a surface area in the range of 1,500 m 2 /g to 10,000 m 2 /g and has a pore volume in the range of 0.1 ml/g to 10 ml/g, wherein the porous organic-inorganic hybrid material with crystallinity is prepared by a method comprising: 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 solvent (step 1); and forming porous organic-inorganic hybrid materials with crystallinity by reacting the reaction solution (step 2), wherein the reaction is conducted under the pressure of about 3 atm or less, wherein the porous organic-inorganic hybrid material with crystallinity is a compound represented by the following formula or hydrate thereof: M3X(H2O)2O[C6Z4- y Z′ y (CO2)2]3 (M=Fe, Mn, Cr, V, Al, Ti, Zr or Mg; X═Cl, Br, I, or F or OH; Z or Z′═H, NH2, Br, I, NO2 or OH; 0 ≦y≦ 4); M3O(H2O)2X[C6Z3- y Z′ y -(CO2)3]2 (M=Fe, Mn, Cr, V, Al, Ti, Zr or Mg; X═Cl, Br, I, or F or OH; Z or Z′═H, NH2, Br, I, NO2 or OH; 0 ≦y≦ 3); M3O(H2O)2X1- y (OH) y [C6H3-(CO2)3]2 (0 ≦y≦ 1; M=Fe, Mn, Cr, V, Al, Ti, Zr or Mg; X═Cl, Br, I or F); or M3X1- y (OH) y (H2O)2O[C6H4(CO2)2]3 (0 ≦y≦ 1; M=Fe, Mn, Cr, V, Al, Ti, Zr or Mg; X═Cl, Br, I or F).
