Abstract

The invention discloses a bifunctional chemical warfare agent degradation material with a bionic enzyme structure and a preparation method of the bifunctional chemical warfare agent degradation material. The bifunctional chemical warfare agent degradation material disclosed by the invention is obtained by reacting polyaluminate cation clusters with a phosphotriesterase-imitating structure with polyacid anions with chemical warfare agent degradation function. The preparation method comprises the following steps: mixing an polyaluminate cation cluster solution with a polyoxometallate solution ofthe same concentrations at the volume ratio of 1:1, standing an obtained mixed solution for three days, and filtering and drying the product to obtain the bifunctional chemical warfare agent degradation material. The bifunctional chemical warfare agent degradation material disclosed by the invention can synergistically exert the effects of polyaluminate cation clusters and polyacids, realize degradation on mustard gas and soman through two mechanisms of hydrolysis and oxidation, and can degrade mustard gas and soman to generate non-toxic products without causing secondary harm; after the bifunctional chemical warfare agent degradation material is recycled for four times, good degradation performance of the bifunctional chemical warfare agent degradation material can still be maintained.

Description

technical field [0001] The invention relates to the technical field of functional materials, in particular to a dual-functional chemical warfare agent degradation material capable of simultaneously degrading mustard gas and nerve chemical agents and a preparation method thereof. Background technique [0002] From the First World War to the occasional chemical weapons attacks today, chemical warfare agents have been developed and applied due to their strong toxicity and lethality. Although under the impetus of the Chemical Weapons Convention, countries have made great progress in the destruction of chemical weapons, and a large number of stockpiles or chemical weapons left over from history have been destroyed. However, compared with other weapons, chemical weapons have lower production costs and sustained lethality, making them an important choice for economically backward countries and terrorist forces when fighting wars or maintaining their own security. Therefore, it is ...
