The design and synthesis 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.

多金属氧酸盐-氧化锆共组装微哑铃，可有效捕获碘

具有高吸收效率，容量和优异的水解稳定性的放射性核素吸附材料的设计和合成仍然是一个挑战。在此，通过一步溶剂热法合成了具有独特的哑铃状3D结构的全无机，簇状核共组装材料（多金属氧酸盐-氧化锆），并进行了放射性核素碘捕获的评估。容易获得的独特的聚氧钼酸盐-氧化锆共组装的微型哑铃（PZCD）不仅能够捕获空气中的汽化碘，而且还能捕获有机或水溶液中的溶解碘。一旦浸入环己烷中，该材料还具有自发释放吸附碘的趋势。在摄取和释放碘的过程中，PZCD的结构均保持完整。
