| 其它 | Seawater uranium extraction is critical to sustainable nuclear energy. However, porous adsorbents that simultaneously achieve ultrafast kinetics and high capacity remain scarce due to the intrinsic trade-off between ion transport and binding density. Here, a topological design paradigm is introduced by constructing phosphoric adsorption clusters within the interlayer nanospaces of porous organic cages (POCs), yielding the phosphate-functionalized POC (PhosCage). This molecular confinement strategy effectively alleviates the kinetic-capacity limitation prevalent in extended crystalline frameworks. PhosCage achieves exceptional adsorption kinetics, reaching equilibrium within 5 min at lab |
