In situ probes of capture and decomposition of chemical warfare agent simulants by Zr-based metal organic frameworks
Zr-based metal organic frameworks (MOFs) have been recently shown to be among the
fastest catalysts of nerve-agent hydrolysis in solution. We report a detailed study of the
adsorption and decomposition of a nerve-agent simulant, dimethyl methylphosphonate
(DMMP), on UiO-66, UiO-67, MOF-808, and NU-1000 using synchrotron-based X-ray
powder diffraction, X-ray absorption, and infrared spectroscopy, which reveals key aspects
of the reaction mechanism. The diffraction measurements indicate that all four MOFs adsorb …
