Abstract

A study was conducted to demonstrate cerium(IV) vs zirconium(IV) based metal-organic frameworks (MOFs) for detoxification of a nerve agent. The rate of hydrolysis observed using a dehydrated version of NU-1000, where ligated water and hydroxide were removed with thermal treatment, was much faster than that of as-synthesized NU-1000. Experiments of this kind showed that Ce-BDC and UiO-66 had similar densities of defect sites. DRIFTS spectra revealed that the sharp peak at 3674 cm^-1 corresponding to the hydroxyl groups on the Zr₆ node of UiO-66 was shifted to 3646 cm^-1 in Ce-BDC, which suggested weaker O-H bonds in the case of Ce₆ node.
