The Impact of Structural Defects on Iodine Adsorption in UiO-66

Radioactive I2 (iodine) produced as a by-product of nuclear fission poses risk to public health if released into the environment, and it is thus vital develop materials that can capture vapour. Materials designed for storage must have high uptake capacity be stable long-term due long half-life 129I. UiO-66 highly readily tuneable metal-organic framework (MOF) which defect sites introduced. Here, defective form (UiO-66-FA) was synthesised presence missing cluster moieties confirmed using confocal fluorescence microscopy gas sorption measurements. The vapour in UiO-66-FA measured thermal gravimetric analysis coupled mass spectrometry (TGA-MS) 2.25 g g?1, almost twice (1.17 g?1) pristine UiO-66. This study will inspire design new efficient stores based upon MOFs incorporating structural defects.
