Recent Advances in Electro/Blow-Spinning Nanofibers for Uranium Extraction from Seawater

Uranium extraction from seawater brings a viable route to secure sustainable nuclear fuel and alleviate environmental issues arising from fossil fuel consumption. In particular, electro/blow-spinning nanofibers have attracted considerable attention owing to their outstanding flexibility, large specific surface area, and facile functionalization capability, positioning them as highly promising platforms for uranium extraction. We first provide a systematic overview of recently developed spinning technologies involving electro-spinning and blow-spinning. Subsequently, we comprehensively evaluate the physical structural characteristics and uranium adsorption performances of these nanofibers and further examine their potential in uranium extraction from seawater. Finally, we identify the critical challenges and future directions for advancing high-performance uranium-extraction adsorbents. This review aims to provide valuable guidance for the design of next-generation nanofiber-based adsorbents for uranium extraction from seawater.
