Embodiments of the present disclosure describe a method of capturing chemical species from a fluid composition comprising providing a metal-organic framework characterized by the formula M.sub.aM.sub.bF.sub.5(O/H.sub.2O)(pyrazine).sub.2.x(solv), wherein M.sub.a is Ni.sup.2+; M.sub.b is Nb.sup.5+, Al.sup.3+, or Fe.sup.3+; x is from 0 to 10 and solv is one or more of H.sub.2O, CO.sub.2, DMF, EtOH, NMP, MeOH; contacting the metal-organic framework with a fluid composition including H.sub.2O, CO.sub.2, and one or more other chemical species; and capturing H.sub.2O and CO.sub.2 simultaneously from the fluid composition.

The present invention is directed to a ligated metal-organic framework (MOF) for use in removing both anionic and cationic species from a liquid or liquid stream. The present invention also provides methods for placing the MOF on a substrate to form a MOF-containing product that can be used in the removal of certain species from a given fluid. The MOF may be a Zr-based MOF, such as NU-1000, for removal of certain anions, such as oxy-anions, or having an attached thiosulfonyl-thiol (—SO.sub.2—S—R.sub.2—SH, where R.sub.2 is an alkyl group) ligand for complexation with certain cationic species in addition to the anions. The substrate may be any substrate to which a given MOF may be attached, including inert polypropylene polymer resin beads, a macroscopic fabric such as a mesh material or mesh filter, and a molecular fabric.

Disclosed herein are lithiated cyclodextrin metal organic frameworks and method of making and using the same. A metal organic framework comprising a coordinated network of repeating units extending in three dimensions, wherein the repeating unit comprises a cyclodextrin, a first coordinating metal cation, and a second coordinating metal cation.

The invention concerns new types of porous coordination polymers (MOF) and a method for their preparation. MOFs have been prepared through synthesis of salts of trivalent cations M.sup.3+, the source of which are aluminium, chromium, iron or yttrium salts, it is advantageous if of chlorides, nitrates or sulphates, with linkers carrying two or more phosphinic groups under presence of solvent. Linkers are phenylene-1,4-bis(R phosphinic acid) (PBPA) and biphenylene-4,4′-bis(R phosphinic acid) (BBPA). For the prepared MOFs, the structure has been tested using x-ray powder diffraction, specific surface and porousness which have been characterised through adsorption isotherm of nitrogen and further the stability of prepared MOFs has been determined using thermogravimetric analysis. All the prepared MOFs have been stable around 400° C. and have contained mesopores or micropores where hydrogen or CO.sub.2, for example, can be stored.

This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has open coordination sites and has been post synthesis modified by partially occupying the open sites with a ligand such as acetonitrile (CH.sub.3CN). The resultant MOF retains at least 40% of its as synthesized surface area after exposure to liquid water at 60° C. for 6 hours. This is an unexpected result versus the MOF which has not been post treated with ligands such as acetonitrile. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.

A detoxification method includes the steps of inducing flow of patient blood through an extracorporeal device inlet and outlet in fluid connection to the circulatory system of a patient. Biological agents including lipopolysaccharide (LPS) contained within patient blood can be detoxified by passing patient blood over a biochemical reactor surface having attached or immobilized Saccharomyces boulardii alkaline phosphatase enzyme, with the biochemical reactor being contained within the extracorporeal device. An acyloxyacyl hydrolase enzyme may also be used on the biochemical reactor surface.
