英文摘要	Roughly 4 billion tons of uranium exists in the oceans, which equates to a nearly inexhaustible supply for nuclear power production. However, the extraction of uranium from seawater is highly challenging due the background high salinity and uranium's relatively low concentration (∼3 μg L -1 ). Current approaches are generally limited by either their selectivity, sustainability, or their economic competitiveness. Here we engineered a biomass-derived microporous membrane, based on the interfacial formation of robust metal-phenolic networks (MPNs), for uranium capture from seawater. These membranes displayed advantages in terms of selectivity, kinetics, capacity, and renewability in both laboratory settings and marine field-testing. The MPN-based membranes showed a greater than ninefold higher uranium extraction capacity (27.81 μg) than conventional methods during a long-term cycling extraction of 10 L of natural seawater from the East China Sea. These results, coupled with our techno-economic analysis, demonstrate that MPN-based membranes are promising economically viable and industrially scalable materials for real-world uranium extraction. © 2019 The Royal Society of Chemistry.
