Abstract

Abstract : Revealing defects, the stability of UiO-67 was studied with SS-NMR as a function of time and activation method/solvent. Abstract : The stability of UiO-67 has been questioned for some time. We have used solid-state NMR to investigate the temporal stability of this MOF. Proper activation is necessary to achieve optimal surface area. However, even with proper activation, the long-term (30+ days) fate of UiO-67 is hydrolysis of the linker-metal bonds and, ultimately, pore collapse.
