“…However, an efficient and economically viable UES is extremely challenging due to the ultralow concentration of U (3.3 ppb) and presence of other interfering ions (Na + , K + , Mg 2+ , Ca 2+ , Cl – , HCO 3 – , etc.) in natural seawater. − Moreover, the accumulation of various plants, animals, and microorganisms in the seawater can strictly affect the application of functional materials in natural marine environments and eventually their UES performance at the given conditions . Therefore, the development of a rational strategy is necessary to design/synthesize robust materials/sorbents with high stability, excellent sorption capacity, and selectivity to obtain excellent U extraction capacity from natural seawater and establish the advanced technology for efficient UES.…”

The sustainable energy supply to the global community remains a great challenge due to the mounting incessant energy demand and environmental concerns associated with fossil fuel-based energy. As per the International Atomic Energy Agency (IAEA), nuclear power will be the only reliable sustainable energy source in the future, and there will be a high demand for uranium (U). Therefore, the exploitation of U from seawater is essential to supply nuclear energy for thousands of years globally. Herein, we discuss some key developments on the design and application of potential sorbents for effective uranium extraction from seawater (UES) under different experimental conditions. Specifically, we focus on the synthesis, characterization, and application of a) organic sorbents (metal− organic frameworks (MOFs), covalent organic frameworks (COFs), membranes, and hydrogels) and b) inorganic substrate (graphene and silica) based composite sorbents. Later, we discuss selected studies encompassing the mechanistic understating of efficient UES using potential sorbents through various analytical and theoretical/computational approaches. Finally, we present future challenges that need to be addressed for the design of compatible sorbents with exceptional properties for the effective UES. We believe that this paper can expand our understanding of the design and application of suitable sorbents for selective UES.
