A 3D hierarchical porous adsorbent constructed by cryo-polymerization for ultrafast uranium harvesting from seawater

Abstract

Large-scale and rapid extraction of uranium from seawater is promising for overcoming the challenge of supply interruption to achieve sustainable nuclear energy production. However, existing uranium adsorbents are limited by...

Uranium and lithium extraction from seawater: challenges and opportunities for a sustainable energy future

“…1–3 Nuclear fission energy, as a mature and low carbon technology, can satisfy the rapidly burgeoning demand for power while lessening greenhouse emissions and maximising sustainability. 4–7 In early 2020, nuclear power accounted for 11% of the electricity generated in the world (∼2500 TW h). 8 Uranium is the main fuel for nuclear reactors, and it exists naturally on land as uranium ore deposits largely concentrated in countries such as Australia, Canada, and Kazakhstan.…”

Alginate-based supermacroporous hydrogels fabricated by cryo-polymerization for uranium extraction from seawater

“…The polymer chains consist of acrylic acid and acrylonitrile copolymerization, and dimethyl sulfoxide (DMSO) is used as a solvent in the polymerization process, which deviates from the principles of green chemistry. 45…”
