Disclosed are a polyacid hybrid compound guided by metal ions and functionalized by a carboxylate ligand, a preparation method therefor and the use thereof in the catalytic degradation of chemical warfare agent simulants. In the method, sodium molybdate, a transition metal, alanine and p-hydroxybenzoic acid are used as raw materials and water is used as a solvent, stirring is carried out under the condition of 80ºC for 1 h, and the solution is left to cool to obtain a product crystal; the prepared polyacid hybrid compound catalyst, 2-chloroethyl ethyl sulfide and anhydrous ethanol are stirred at room temperature in a reaction vessel for a short amount of time, an H2O2 solution is added, and same are reacted under stirring for 5 min to complete the catalytic oxidative degradation of the 2-chloroethyl ethyl sulfide; and the catalyst, diethyl cyanophosphate, N,N-dimethylformamide and water are fully stirred in a reaction vessel, and same are reacted for 10 min to complete the catalytic hydrolytic degradation of the diethyl cyanophosphate. With regard to the catalytic degradation of the two chemical warfare simulants, the prepared polyacid hybrid compound catalyst has the advantages of a high conversion rate and high selectivity, and being reusable. |
