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.
