Polyoxometalate–Zirconia Coassembled Microdumbbells for Efficient Capture of Iodine

of radionuclide adsorbent materials with
high uptake efficiency, capacity, and excellent hydrolytic stability
remains a challenge. Herein, an all inorganic, a cluster-nuclei coassembled
material (polyoxometalate–zirconia) with a unique dumbbell-like
3D structure was synthesized via a single-step solvothermal approach
and evaluated for radionuclide iodine capture. The easily obtained
unique polyoxomolybdate–zirconia coassembled microdumbbells
(PZCD) are not only capable of capturing vaporized iodine from air
but also dissolved iodine from either organic or aqueous solution.
The material also possesses the tendency to spontaneously release
adsorbed iodine once immersed in cyclohexane. The structure of PZCD
remains intact during both the uptake and release of iodine.
