Metal ion-directed carboxylic acid functionalized polyoxometalate hybrid compounds, and their preparation method and applications in catalyzing the degradation of chemical warfare agent simulants. In the synthesis, Na.sub.2MoO.sub.4, p-hydroxybenzonic acid (PHBA), alanine (Ala), KCl, transition metal cations and As.sub.2O.sub.3 as raw materials and water are used as solvent. At room temperature, 2-chloroethyl ethyl sulfide (CEES) and the prepared polyoxometalate hybrid compounds were mixed together in anhydrous ethanol and stirred, and H.sub.2O.sub.2 was subsequently added into the reaction system. The catalytic reaction for the degradation of CEES was finished within 5 min under stirring. In the catalytic hydrolysis of diethyl cyanophosphonate (DECP), the catalyst, DECP, DMF and H.sub.2O were put together and mixed fully. The prepared polyoxometalate hybrid compounds have the advantages of high conversion, high selectivity and easy recyclability in catalyzing the degradation of two types of chemical warfare agent simulant.

Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. Crystallization may be problematic in some instances when secondary binding sites are present in the multidentate organic ligand. Multidentate organic ligands comprising first and second binding sites bridged together with a third binding site comprising a diimine moiety may alleviate these issues, particularly when using a preformed metal cluster as a metal source to form a MOF. Such MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety. Particular MOFs may comprise N,N′-di(1H-pyrazol-4-yl)ethane-1,2-diimine as a multidentate organic ligand.

The present invention provides a magnetic Fe.sub.2O.sub.3 nanosphere with PNH surface modification and application thereof in water treatment. First, 2,2-bipyridyl-5,5′-dicarboxylic acid is reacted with thionyl chloride to obtain 2,2-bipyridyl-5,5′-diacid chloride; then 2,2-bipyridyl-5,5′-diacid chloride and 1,4,8,11-tetraazacyclotetradecane react in the presence of triethylamine to obtain a polynitrogen heterocyclic polymer; the polynitrogen heterocyclic polymer is added into an aqueous solution with iron salt to obtain a magnetic Fe.sub.2O.sub.3 nanosphere with PNH surface modification which has strong light absorption ability, which improves its ability to catalyze in degradation of tetracycline under visible light, so that the pollutants are removed from water.

This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has been modified by substituting some of the BTC ligand (1,3,5, benzene tricarboxylic acid) with 5-aminoisophthalic acid (AIA). 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 containing only the BTC ligand. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.

The linking occurs through diamine and dicarboxylic acid linkers. The zinc-based metal organic framework may be deposited on a transparent conducting film and used as a photoelectrode for photoelectrochemical water splitting.
