Use the Cpo-27 to Degrade Simulant of Nerve Agents

Abstract

EN] Metal-organic frameworks are a recently-identified class of porous material, consisting of metal ions linked together with organic bridging ligands. The porosity of these materials allows the absorption of suitable molecules into the structure. The [Co2(C8H2O6)(H2O)2]·8H2O MOF(CPO-27) has been synthetized by solvothermal methodology following the procedure described by Dietzel et al.[1]. Activation of MOF was carried out in order to remove water molecules linked to the cobalt; consequently metal active sites are available to perform catalytic reactions. Well-known simulant of nerve gases, such as diethylchlorophosphate (DCP) and dimethylmethyl phosphate (DMP), are extremely harmful and stable, and consequently, hardly to degrade. In order to evaluate the potential capacity of the CPO- 27 as catalyst in the degradation of DCP and DMP, several attempts have been carried out by using different media. The reactions were followed by 1H, 13C, 31P NMR and XRD spectroscopies to monitorize the results
