Radioactive iodine exhibits medical values in radiology, but its excessive emissions can cause environmental pollution. Thus, the capture of radioiodine poses significant engineering for the environment and medical radiology. On the cover image, a Th-based MOF (Th-BPYDC) with octahedral structure was synthesized by hydrothermal methods, consisting of 12-linked polyhedral [Th6(μ3-O)4(μ3-OH)4((H2O)6]12+ clusters, abundant bipyridine units and large cavities allowing diffusion and transport of the guest iodine molecule. Th-BPYDC exhibited an effective uptake capacity for I2 vapor and dissolved I2 in cyclohexane, surpassing its corresponding analogue Th−UiO−67. The bipyridine units boosted the adsorption performance, resulting Th-BPYDC with good reusability and high stability. Therefore, the construction of nitrogen-rich bipyridine units on Th-MOF can immensely improve the adsorption capacity for radioiodine, and the feasibility of this strategy provide a new idea for radioiodine capture in spent nuclear fuels treatment.
