Abstract:
An adsorber containing porosity organic/inorganic hybrid is provided to remove impurities of organic/inorganic mixture nanoporous materials and to increase surface area the organic/inorganic mixture nanoporous materials by processing it using ammonium chloride or potassium fluoride. An adsorber containing porosity organic/inorganic hybrid comprises steps of: mixing metal precursor, organic compound acting on ligand, acid and solvent and manufacturing a reactant mixed solution; irradiating microwave to the reactant mixed solution over 100°C; processing the porosity organic/inorganic hybrid using an inorganic salt or solvent. The acid is inorganic acid except for hydrofluoric acid.
Abstract:
A manufacturing method of porosity organic and inorganic hybrid is provided to manufacture and refine porosity organic and inorganic hybrid by an eco-friendly method using a new manufacturing process which does not use a hydrofluoric acid at all. A manufacturing method of porosity organic and inorganic hybrid comprises steps of: 1) manufacturing the reactant mixed solution by mixing a metal precursor, an organic compound acting on a ligand, an acid and a solvent; 2) heating the reactant mixed solution over 100‹C by electric heating or irradiating a microwave; 3) refining the porosity organic and inorganic hybrid by processing obtained the porosity organic and inorganic hybrid in the step 2) as inorganic salts.

A preparation method of surface functionalized porous organic-inorganic hybrid materials that can be used in adsorbents, gas storage bodies, sensors, membranes, functional thin films, catalysts, and catalyst carriers is provided, and a catalyst composition for an acid or base reaction, hydrogenation, dehydrogeneration, a carbon-carbon bonding reaction, or an oxidation reaction by using the surface functionalized porous organic-inorganic hybrid materials or porous organic-inorganic mesoporous materials is provided. A preparation method of surface modified porous organic-inorganic hybrid materials is characterized in that the surface modified porous organic-inorganic hybrid materials are prepared by bonding organic materials, polyoxometalates, ionic liquids, organometallic compounds, or mixtures thereof having functional groups selected from an amino group(-NH2), a thiol group(-SH) and a phosphoric group(-PO(OH)2) to porous organic-inorganic hybrid materials with coordinatively unsaturated metal sites or to coordinatively unsaturated metal sites of porous organic-inorganic mesoporous materials. The porous organic-inorganic hybrid materials are polymer compounds formed by bonding core metal ions to organic ligands and have molecular-sized or mamo-sized pore structures, and the porous organic-inorganic mesoporous materials have coordinatively unsaturated metal sites and pores with a pore size of 2 to 50 nm by substituting dissimilar metals. Core metal precursors of the porous organic-inorganic hybrid materials are one or more metals selected from Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Hg, Mg, Ca, Sr, Ba, Sc, Y, Al, Ga, In, Tl, Si, Ge, Sn, Pb, As, Sb and Bi, or compounds thereof.
