Uranium is a critical resource in the development of nuclear energy, and its extraction from natural seawater has been identified as a potential solution to address uranium resource shortages. In this study, hierarchical meso‐/micro‐ porous metal‐organic framework functionalized with phytic acid (PA) microspheres (denoted H‐UiO‐66‐PA) are rationally synthesized for efficient uranium extraction. This unique design allowed for a large adsorption capacity and fast adsorption kinetics, making it a promising material for uranium extraction. Due to the hierarchically porous structure, H‐UiO‐66‐NH2 materials not only provide more sites for grafting PA, and thus enhance the adsorption capacity, but also facilitate the rapid diffusion of uranyl ions which can quickly and effectively access the interior of the H‐UiO‐66‐PA adsorbent. Therefore, the obtained H‐UiO‐66‐PA can achieve an impressive absorption efficiency of 6.76 mg g−1 in actual seawater within 15 days. Meanwhile, the H‐UiO‐66‐PA possesses a good adsorption capacity for uranyl ions in the five adsorption/desorption cycles. This work proposes a feasible strategy for constructing functional hierarchical porous MOFs for uranium removal.
