Uranium extraction from seawater is a major barrier for the development of nuclear power to cope with the energy and climate-change crises. Here, we report the integration of conductive chains into porous adsorbents, which provide the expended electric field to cover the micrometer-sized adsorbent particles under alternating currents. On the basis of the superiority (large accessible area and tailorable adsorption site) of porous adsorbent for chemical adsorption, the live media promote the migration and enrichment of uranyl ions into the porous architecture. The superstructure shows 2–3 orders of magnitude faster kinetics than the polymer adsorbents under physical diffusion. Such an adsorbent enables a strong affinity that captures 99.1% of uranium in 120 min (from ∼4.4 to ∼0.04 ppb). It achieves the uranium extraction standard (6.0 mg g⁻¹) in ∼16 days and captures 13.0 mg g⁻¹ of uranium in 56 days from natural seawater.

从海水中提取铀是发展核电以应对能源和气候变化危机的主要障碍。在这里，我们报告了将导电链整合到多孔吸附剂中的过程，这些吸附剂提供了扩展的电场，以覆盖交流电下的微米级吸附剂颗粒。基于多孔吸附剂在化学吸附方面的优越性（较大的可触及面积和可调整的吸附部位），活性介质可促进铀酰离子向多孔结构的迁移和富集。在物理扩散下，上层结构的动力学比聚合物吸附剂快2-3个数量级。这种吸附剂具有很强的亲和力，可以在120分钟内（约4.4至0.04 ppb）捕获99.1％的铀。达到铀提取标准（6.0 mg g^-1）约16天，并在56天内从天然海水中捕获13.0 mg g ^-1铀。
