A nerve-agent simulant based on a phosphate ester is hydrolyzed using a MOF-based catalyst. Suspensions of MOF-808 (6-connected), a material featuring 6-connected zirconium nodes, display the highest hydrolysis rates among all MOFs that have been reported to date. A plug-flow reactor was also prepared with MOF-808 (6-connected) as the active layer. Deployed… (More)
Figure 2. Hydrolysis of DMNP. a) Hydrolysis reaction of DMNP by MOF-based catalysts, b) in situ 31P NMR spectra indicating the progress of hydrolysis of DMNP (d=¢4.4 ppm) to dimethoxy phosphate anion (d=2.8 ppm) in the presence of 0.3 mmol of MOF-808 (6- connected) at room temperature (reaction conversions at 30 s are obtained by filtering the reaction mixture and measuring the 31P NMR spectrum of the filtrate because the NMR sample requires more than 30 s to prepare), and c) hydrolysis profiles of DMNP in the presence of MOF-808 (6-connected) at different concentrations (circles), after removal of catalyst by filtration (pink diamonds), and without catalyst (black squares).
